Feature Request: Multi-MeshProjectedMask Image Change

In a Layering Project, I would like to be able to select multiple mesh projected masks in the layer stack (which works fine) and change the image for all selected mask layers in one fell swoop.

Justification

Currently when selecting multiple mesh projected mask layers in a layering project, if you change the image input to your desired image, the only mask layer affected is the last one selected.

Implementation Details

Select as many mask layers as you want, so long as they are all of the same mask type (e.g.- Mesh Projected Mask), the changes made in one of those mask layers is applied to all selected mask layers. Could also be useful for Vertex Color Masks as well.

Thanks @skrawnybynature for your feature request!
