Before I request a feature, let me ask if it already exists 
I am currently reading The Necessity of Prayer by E.M. Bounds, both on my desktop and on my android. I have a notes document that I use for my notes and certain highlighter options. This works well on the desktop, but I haven't figured out how to add notes from my android that will be part of the desktop notes document and not some random note.
My question is, When on my android, can I write a note and specify which note document I want it to be a part of? (Some documents have more than one note document associated with them.)
