Sponsor Grid Controls

Feature request: include sponsors by specific category

Right now the Sponsor Grid component lets me exclude sponsor types (Main, Category, Talk, Custom Category, Uncategorised), but there's no way to include only a specific category.

What I'd like is an allow-list control: let me pick one or more categories and show only those sponsors, instead of showing everyone and hiding the rest. Filtering by inclusion rather than exclusion would make it much easier to build targeted sponsor widgets.

More granular include/exclude controls here would be extremely useful.

Thank you
