Time Management for do until loop

[Anonymous]

Hi,

I designed an approval process about 10-11 steps. But, It takes too much time to end a process. Sametimes, one step of approval takes 1,2  weeks. So I want to limit each step 3 days mostly. 

I used start and wait for an approval in the do until loop. And I connect the outcome of the approval to the do until. So I cannot make it continue. If I would add more than one condition like while loop, maybe I can fix it. How to solve this issue? 

Thank you.
