Needs a the ability to switch sets without interruption back

This app is alright, yet I find it needs the ability to switch from one workout set to another without interrupting the current one. I have many sets and I find having to stop the time set that is going to prepare for another one frustrating. As a fitness professional It needs the switch without interruption feature back.
