[Feature Request] Option to add recipes to collections

[Nino]

Hello,

I'm missing the possibility make collections.
I'd like to be able to add multiple recipes to some cookbook.
Of course I could misuse the "Source" or "Kitchen" entry for it as these fields are not crucial to me.
However it would be nice to have an entry field to add a recipe to one or more collections.

Any thoughts about this?

Bye
Nino
