Can I invoke different sub-processes using one call sub-process?

Hello folks,
Can I use a call sub-process to invoke different reusable sub-processes based on the variable that is passed? Or does the call sub-process work strictly with one re-usable sub-process. Will be happy to hear from you. I also intend to run multiple parallel instances as shown below.
