Exposed Inputs default to baked maps?

I'm creating quite a few materials with exposed parameters using the Painter Filter (w/ additional mesh maps) template. This works great, as I can load a model in, bake the relevant maps (usually AO & curv), fine tune everything, then replace the baked images with my inputs and export to Painter. However, if I want to tweak anything after, I have to go through the process of swapping the links back to the bakes, editing, back to exposed parameters, export. Since all of these inputs are empty (black/trasnparent) by default, it would make a lot more sense for SD to default to your baked maps as an override to these inputs, or at least offer the option to.
