Exchange reference sketch of an extrude by relations or ProProgram?

As the title say, is there any way to exchange the reference sketch of an extrude with us of relations or ProProgram?

The reference sketches I want to exchange from/to are all defined as individual sketches above the extrude feature in the model tree...

I know I kan create different extrudes for all the sketches, and then use ProProgram to select which one to use, but that is not what I am lookin for here...

Any ideas?

Thanks!
