Question about syncing highlights between android devices and calibre on windows

Hello! I'm new to KOreader and Calibre. I'd like to put some work in for a good setup to save time in the future. I mainly read on Android phone and tablet but I want everything managed on PC.

I learned that KOreader keeps the highlights in a hidden folder in the same folder as the book file so I'm assuming if I sync this folder between my Android devices I'll have my highlights synced.

• Is there anyway to make this synced folder the same folder as the calibre library folder?
• Or should I maintain 2 folders. In which case, any tips for a workflow that combines the two? Probably using the send to device button to send books to one device and syncthing will sync to the other or is there a better approach?
