Is it possible to scale a sprite, and have that new size be set as scale 1?

Hi all

I've been making a game with lots of sprites which use high resolution textures.

I am hoping to give the option to replace these textures with lower quality ones for performance benefits. I would have to scale them up (half assets to scale * 2).
However, there are times when I tween the scales on sprites. (tweening to scale 1.5 would have made a sprite larger, it would now make it smaller)

A quick way of solving this would be to scale the sprite straight away, and then lock that as the default scale (1) so I wouldn't have to make a large amount of changes.

Is this possible? I would prefer to not scale up the textures themselves, as I believe this would have the same performance as using the high resolution textures in the first place.
