Thank you and a request

Hello, I use this app to structure music practice, and it is great! However, I have sequences that are quite long (90 minutes). Is it possible to add a feature in the app so that one can start from partway through the sequence (or add a back and forward button that would allow us to skip to the wanted element or go back during the sequence?) If I get interrupted and forget to pause, Im stuck with a choice between starting over and editing the sequence... Thank you! Great app!
