Career Opportunities Opportunity Market place - Can we add Job DFFs to the filters?

We are looking to add Job DFFs as part of the search filters in Opportunity market place. Please find the screenshots below.

Just similar to Job Function, Job Family we would also like to add Career Band/ Level (a Custom DFF) to the search filters.

I tried searching in VBCS and could not find any reference to add Job DFFs.

Can you please help if this is something we can do?
