Scan Editing / Mark Up Within the App Before Sending

It would be great to be able to edit scans in the Rocketbook app that would then automatically overwrite the file in cloud storage. Say for example I have already scanned a page and want to add something, I just go into the app, click on edit and write/draw something on the page and if possible, overwrites the file in my cloud storage, if not, just creates a new file.
