Banca Sella does not direct register shares, so you need to transfer your shares to another broker that can DRS transfer.
Banca Sella may charge a fee for each Basic FOP Transfer. This means each time you want to transfer a specific stock (no matter how many shares) you are charged a fee.
A popular route has been through Interactive Brokers (IBKR), as they are available internationally and can DRS transfer for $5(US). The Italian brokers that are known of that can DRS transfer are Directa SIM ($75 fee), and MeXeM ($5 fee).
The quickest way is to open an Interactive Broker account, buy a share, and request a DRS transfer (link to guide here). While you wait for your Computershare account to be created, you can transfer your shares from Banca Sella to IBKR with a Basic FOP Transfer, then from IBKR to Computershare via DRS transfer for a $5(US) fee.
How to Transfer:
Once your shares are settled in Banca Sella, you can start the process by making an appointment to go into your local branch and fill out an outbound transfer form. Then you notify IBKR by creating Letter of Instruction with their forms.
Call Banca Sella and book an appointment in your local branch to fill out the outbound transfer form.
Go into the bank, fill in the form with the help of the bank employee.
Provide IBKR's contact email for share transfers: firstname.lastname@example.org
Banca Sella will then start to process the transfer request. Now you can notify IBKR so they know the transfer is coming.
Making the Letter of Instruction with IBKR:
Login in your IBKR account, and click on “Transfer & Pay” from the top menu and select “Transfer Positions”.
On the next page select “Incoming”.
On the next page select “All Other Regions” from the drop down menu.
On the next page select “Basic FOP Transfer".
Select BANCA SELLA on the drop down list.
For “Your Account Number at the Financial Institution" put your Banca Sella account number.
For “Name of Account Holder at Financial Institution“ put your full name as defined on your Banca Sella account.
Select the Account type (most likely individual).

On the next page, define how many shares you'd like to transfer and click on “Save and Finish".
On the next page you'll see a summary of the transfer. Write in your name as it shows on the page and click on “Continue”.
Interactive Brokers will then generate a Letter of Instruction for you. However you will not need it as Banca Sella already knows to transfer the shares and to contact IBKR at firstname.lastname@example.org
Banca Sella and IBKR should now start communicating with eachother about the transfer. The transfer will be processed within 1-2 weeks. You will receive an email confirming that the transfer was successfully performed. If you are unsure you can phone Banca Sella on 800.050.202
