Multiple times in the past, my team has added new files to our git repository and Gearset dose not pick them up as existing in the repository when we do a comparison.

Select your git repo/branch as the source, select the sandbox you want as a destination, the comparison page says "fetching repositories", but it doesn't seem to actually pull the updated data from the branches. My comparison builds fail because the new file isn't included in the comparison. Gearset usually ends up picking them up in ~12 hours but it's a huge workflow blocker when a tool doesn't have a way to update its source data.
It would be great to have a button to manually fetch/pull branch data in gearset to get around this instead of just having to "wait until Gearset sees it".
