Make MSPC variation thumbnail different to the image that is added to the Fancy Product Designer

I have set up the Fancy product designer and integrated the Multi Step Product Configuration plugin to create a set up very similar to the Sneakers example on your site.

My set up requires 3 Fabric options for each product. I have set the fabric areas up as separate layers and used the Replace element to make the options change across all views.

My problem is that you can only associate one image with the variations, so the thumbnail and image that is applied to the Fancy Product Designer is always going to be the same. It would be much better if you could add a thumbnail and FPD Layer image for each variation. This would allow me to use a swatch for the fabric thumbnail, and a transparent png with associated colour options on the FPD.

If we were to take this one step further, a third image would also be useful to add an associated texture layer above the previously mentioned FPD layer. This would then allow for a fabric variation to have it's own swatch in the MSPC steps, a transparent png in the FPD with associated colours for that layer, then an associated texture layer to give the visual representation of the fabric selected.

I know this is a lot to ask for, but I'm sure others will come across the need for fabric variations when building custom products.
