I looked into this and it seems possible with DPL. It seems it is not enabled on your Wiki, so you will need to request it to be enabled through Contact. You can read more about DPL here and the particular feature you're after is category intersection, and I found documentation about it here.

Hope this helps, and let me know if you need further help with this feature!
