Move a mask/unmask selection shape?

[JFK]

Is there any way to draw a shape to unmask say, a circle, and then drag that selection on the map? So, one could draw a circle to unmask a 'torch' radius, and then drag in along as the torch is moved, unmasking the same size/shape each time it's released from the drag. It would be great if the vacated shape (where the circle was before moving) was 'filled in' and masked, however that's not necessary, as the GM can easily do that manually.
The ability to keep the size and shape would be useful for simulating light sources, and also for moving along corridors where the light ends on the confining walls.

Thanks!

This functionality is not currently available, just freehand unmasking/masking.

This is kinda covered by the "Map - Dynamic Light Sources" item in the FG wishlist: https://fg2app.idea.informer.com/
