Roblox engineers are actively investigating possible ways to solve this issue with automation. There was a post on this a few months ago confirming that, using the new DataStore userId parameter, you will be able to use the Creator Dashboard to remove the data by simply confirming its removal. It may be a little tedious to manually confirm the deletions still, but it is a lot better than the current situation. 
Who knows, they may even add a permission to allow other people to handle the requests for you.
