I think it would be very helpful, to be able to change your mask stroke to a stamp like the line tool.

I am creating a map. Where the islands are all a tall cliff. Sort of like the first photo attached.

Its a pretty big map. I can see that I can use the line tool, to draw in the cliff stamps. I would like to be able to change the stroke in my mask tool to just be the cliffs stamp, which would make it much easier and faster for me. Instead of just changing the stroke to one color.

See next photo of part of my island. (Top is the mask stroke. Bottom is me drawing the line over top.)

And the next photos are my settings.
