[Feature request] Add selected content to the top/bottom of a fixed note instead of creating a new note

[bdalia]

Aside with my note system, i usually mantain a huge checklist of tasks in a special note called Flashboard.
I use the Flashboard daily to manage all my activities.

When i complete some tasks i simply delete them from my Flashboard and here is where my feature request starts: instead of delete completed tasks, it would be very useful to move them in a "fixed log note", by adding the selected content at the top, with a timestamp/tiltle.

This plug-in is very near to my need, the only difference is that it create a new note with a selection. So it would be fantastic if it will be implemented to add the selection to an existing note instead of creating a new note (may be with a separate command/hot-key ?).

This is an example of how the fixed log note may look after the execution of the feature for two times:

## okTicket
- [x] [[Analisi Funzione Regala biglietto su okTicket]]
- [x] okTicket App test
- [x] Feedback system okTicket *after pilot*
- [x] Ingressi liberi sui combinati. Va previsto che per alcuni subticket non sia necessario prenotare. Tutto questo ha impatti sul workflow che vanno studiati.

I added the 4 asterisks (a line separator) at the end of each chunk for a better visually separation between chunks

Kind regards,
