グループカテゴリのモデレーターを複数設定する機能

[JammyDodger]

I think this is for performance reasons:

Note this is a current limitation of the category review that only one group can be granted review access per category as it makes the design of the feature much simpler with higher performance. If none of your existing groups are a good fit you can always create a new group just for this specific purpose.

Could you create a specific group for your category moderators?
