Activiti / Camunda change boundary timer with variable

Question

I got a special question regarding timer boundary events on a user task in Activiti/Camunda:

When starting the process I set the timer duration with a process variab

Answer 1

Solution is to have 2 out going sequence flow, one should be from boundary timer on task and another one should be from task it self, as shown in diagram added by @theFriedC. See following image also.

Then you can use some exclusive gateway on 2nd sequence flow and reroute that back to same task with a new timer value.
