Convert direct download license to App Store license?

Hi, this is a long shot, but I bought TaskPaper 3 via the product quickly following the “Buy…” wizard flow and now wish I had downloaded via Mac App Store just for the convenience (being prompted for upgrades, etc). Is there any way to switch my license to MAS?

Sorry I can’t do that conversion. But the version of TaskPaper that you download from my website should also prompt you to download updates periodically.
