is there a way to NOT inactivate concurrent tasks?

System

this probably sounds like a strange question, but I have 4 concurrent/parallell group tasks, each with a timeout value...the timeout successor task for all 4 group tasks is the same external task, named "timeout_reset"...

in a nutshell, all "timeout_reset" does is reset the timeout value on the task that timed out, send an email notification of the timeout, and then re-activate the task that timed out...

it seemed efficient to use a single "timeout_reset" task to handle any timeout, but it apparently has an undesirable side effect in that when it is activated, it inactivates not just the task that transitioned to it, but ALL of the remaining active concurrent tasks, just because they are also possible predecessors to the same task...

all examples/documentation indicate that the <inactivate> node is to inactivate any tasks that may be active, but do not directly transition to the task that was activated, so is of no help to me in resolving this "side effect" of efficiency...

short of putting in 4 separate timeout tasks for unique transitions from the 4 concurrent tasks, is there any way to NOT inactivate the concurrent tasks that have not timed out?

thanks in advance,
