Any way to mass delete props?

[NiceGooch_PSN]

Can you delete more than one prop at a time? Or is there a way to not have to press and hold circle to delete a prop?

pick "blank canvas"

but i already filled up the blank canvas, is there any way to get a new one?

Would really like a feature like this! I also filled up my blank canvas and now have to delete each individual prop on the other stadiums to start fresh. The presets are a good idea, but I would love more blank canvases or the option to mass delete.

I found deleting on Minor Canvas and Cornfield takes the least time, for now.
