Integration request

Good morning,
I’d like to know if it’s possible to filter the category where the plugin works.
At the moment it’s possible to select to view the plugin in ALL posts, but if someone (or most I think) has got different kind of category, it would be very useful to be able to select which kind of category to include in selection.
I would be willing to pay to have this integration! So if You have any solution please reply me.
Thank You for Your attention.
Best regards
Alessandro
