Feature request — Bidirectional sync of notes with Dropbox and Evernote

Thank you so so much for integrating sync to Dropbox and sync to Evernote into the Notes app. It really is extremely helpful to be able to make notes on our Boox devices and then sync them to use on another device. However, these sync features are entirely uni-directional. If one forgets, and makes changes to the PDF in Dropbox or Evernote using another device, and then syncs Boox again, the changes from that other device are lost.

Would it please be possible to have bi-directional sync with Evernote and Dropbox, so that we can edit our Boox notes on other devices if need be?
