Custom notification tips per category

Apologies if this was discussed before.

It will be great if we could set ours custom notification tips in topics creator category specific.
As we can pin topics per category / subcategory inmagine that we can pin tips per category.

Here is one of scenario used.

We have category gallery where users posts pictures.
Recently we start using theme which provides gallery plugin.
When user starts writing new topic in gallery category , I want to tip him to use category button.
