How to set Product as a subsequent document of a transaction

Hello gurus,

I need to create a Product (PRD_SRV), as a follow-up document for a Task (BT125_TASK).

Let's consider a transaction type ZTAS, ( Category 101 Task) for which we have to create subsequent documents. In customizing, Customer Relationship Management >Transactions>Basic Settings> Copying Control for Business Transactions > Define Copying Control for Transaction Types, we need to customize the follow-up documents allowed for this transaction ZTAS.

Searching among the available target transactions, I cannot find PRD_SRV object (I assume because obviously it is not a transactional object), but there are objects such as IUPD (Product Determination Object) which are available, and which are not transactional objects neither. I customized the 2 target transactions to test the behaviour:

However, with this configuration, the option to create a PDO as a follow-up document does not appear, and the system navigates directly to a follow-up task.

Is it possible to create, from a transactional object such as a Task, a follow-up document that is not a transaction?

Best regards.
