Feature request: optional "smother" for upscaled picture

I create all my tiles and pictures i need in my löve projects in aseprite. In Löve some of them become scaled up using “linear” interpolation. It would be helpull to aply a similar filter in aseprite.
I would like to have one or more tiny button - lets say right to the 2 symmetry buttons - If i press one of the filter buttons the filter becomes active. When i do something to my picture, like moving, zoom change, tool change, and so on, the filter becomes deactivated automatically.

What do you think about this idea?
