[Throwaway]

I have cases that are awaiting a calendar date, is there a way I can reassign any case to set another user as @@USER_LOGGED?

It only allows me to reassign to supervisors manually, even though they are on the assigned task (when it's in transition).

You can use this sample process to do reassignment:

I'm not sure how ProcessMaker's Cases::reassignCase() function handles paused cases, so you will have to try it and see what happens.
