Parameterize Connection Strings

I want to be able to dynamically change the connection string for a copy activity based on an environment variable (ex: DEV, QA, PROD).

Instead of using the drop-down for connection in the copy data activity, I'm looking to parametrize it.

The issue occurs after I create that dynamic connection string, I'm unable to select the connection type of SQL Server. I only get the options of Lakehouse, KQL Database or Warehouse.
