Filter applied on adaptive family doesn't work

Hi all!
I created an adaptive family of a pile wall with a pile cap and placed it in main project. I am now trying to apply a filter to assign color but it is not working.

Is it possible to apply filters to adaptive families? If so, what would be the best way?

Additional question of setting the adaptive family type. I would like to assign it a foundation type but has no option within the adaptive family window. The pile I created in generic models I assigned a structural foundation type and marked the share button which I thought would share different details along the chain of nested adaptive families (two nested families: the main pile and the adaptive single pile to be nested in the final arrayed adaptive family) but eventually it is loaded into the project as generic models.

Would there be a way to assign it a structural foundation type?

Structural foundations are system families (like walls) and only defined in the project. They cannot be created outside of the project environment as a loadable family.
