Revit :: Schedule Filters - Multiple Filters

I am working on a dormitory project and need to provide a required light and ventilation schedule.  I have figured out how to create a schedule for each level, but I want to isolate only the Dormitories and the Kitchenette (weed out all the other rooms such as corridor, elevator, storage, toilets, showers, stairs, trash, electrical, etc.).
 
I tried using seclusion filters, but there are too many items to exclude and cannot fit them all into the 4 filter categories.  I am trying to just get the rooms that begin with 'D' and 'K'.  I tried providing the variable 'Begins With' for D and in the next line 'Begins With' K, but then nothing shows up.
 
Is there a way to provide information to the filter that would allow it to show only rooms beginning with D AND K?  I cannot seem to get it to work.  I have been playing around with separation values within one filter category (i.e. 'Begins With' D, K) but apparently you cannot add multiple variables within one of the filter items.
