Sync active pages between Kobo devices using Calibre?

Hey there. I have two Kobo devices, and use Calibre to sideload the exact same library of books on each. I'm looking for a way to sync progress between devices - dir/filenames are the same on each. I believe I have my progress sync to Calibre already, but I haven't found it to update my position across devices. Hoping there's a solution.

Thanks for any suggestions!
