Suspend processes called by main process with Call Activity

Hello all.

I have a process that has a Call Activity right after the start event. The process that is called depends on a variable coming from the start event.
So, I have a number of processes that can potentially be started from the call activity and in called element I use ${protocol}, instead of a hard-coded string.

Is it possible to suspend some of these called sub processes? I tried suspending one from cockpit but after starting the main process, it called the suspended one and it started normally.

Is it possible? Can I do this functionality somehow?

Thank you!
