I'm not 100% sure I understood what you need, but here's an idea.


Make your model return the header data you want to filter upon as some 
"hidden" role of come column. Then put a QSFPM on top, filtering on that 
column and that hidden role.

If you can't modify the source model, place a QIdentityProxyModel in the 
middle with a custom data() override.
