How to add a default tag for notes?

[wsw70]

I am planning to use Karakeep for ad-hoc notes (and notes in general) I would like to automatically tag them when entered from the web interface ("new item").

Is it possible to add a default tag for them? (#note or similar)
Other elements in Karakeep will come from either a browser extension or an Android app, so there is a way to distinguish the source
