Filter Velo Commands

Hello, I am trying to achieve a store page that changes a picture and text box on specific product models, but not on price, color, or sizing. The way I have gone about it was creating multiple pages for each type of product, and from there you can filter the model, color, pricing, etc. However, I realized that when you change collections for a grid store gallery, your filters reset, and you have to manually create them all over again. Is there any way that I can make certain filters not reset when changing collections? If not, I am trying to achieve a system (which is even better), where on certain selected filters in the grid gallery, the heading changes to a different state. I have gone about this by using a multi-state box that changes the items I need to change, but I do not know how to code in an onfilterchange command (or if it is possible) . It would also have to default back to a state if two filters are selected, without considering certain filters (sizing, color, price). Thank you, appreciate all input, if you can think of a better solution, please let me know. Here is a link so you can see what I am talking about better (keep in mind is in development so there are lots of issues).
