Whitelist type option to keep tabs from sleeping?

Awesome app so far, thanks a lot. One thing I noticed though is it is making my Google Sheets tabs and a couple other things sleep when they are left doing automated things.   Is there a way that you can create a whitelist to keep tabs open?  I need to be able to have API nonsense running for hours on end at times and it keeps shutting everything down and preventing what would have been an entire weekend worth of work last week, for example.
