[[Feature Request]] Custom Images for Shapechanging

[RinVindor]

Is your feature request related to a problem? Please describe.
Currently if you want to change the icon for a creature that changes forms, you have to manually set it or use a macro.

Describe the solution you'd like
Having the option to set the image for each form you have would be fantastic for whenever a creature changes forms and when the form is selected that image is now the new token, changing the token that is on the map.
