Inclusion of "S" character in e.g., $(atem:mp_index_1) precludes easily getting image feedback using "atem: Media pool: Preview image from variables"

Hi team!

Always appreciate the hard work, and very excited to see new stuff including the atem: Media pool: Preview image from variables feedback in the new module.

A small issue: It would be great to be able to use the preview image of the currently selected media pool image as feedback. Unfortunately, the relevant internal variables (e.g., $(atem:mp_index_1)) seem to include the letter S before the image number, which means the variable can't be used directly in the atem: Media pool: Preview image from variables feedback.

The feedback also only seems to accept a variable name rather than an expression, so it's not straightforward to substring out the S while setting up feedback.

I've hacked something together using a custom variable that gets updated by a trigger, but wonder if perhaps the variables like $(atem:mp_index_1) could just yield the number rather than include an S. Another possibility would be if the atem: Media pool: Preview image from variables feedback could accept expressions; this would also make it easy to do things like make a button showing an image preview of the next still, which could be useful for some.

Many thanks again. Also happy to provide more details/comments if/as useful.
