You could use the “Function” parameter for exterior and interior walls as a Filter.
Scheduling with Stacked Walls has always been a limitation and hence why really only used at concept stage for area and overall volume quantities.
You could create some new wall parameters directly in the schedule to meet you need exactly for filtering?
You can also use a Material Schedule to break walls down further into their layers which may give more filtering options.
