Any way to reload textures?

I really like the custom textures feature of this emulator, it’s fun to mess around with it and replace textures in games, but for the life of me I can’t figure out a way to reload the textures every time i edit one.

Right now I’m reloading the entire game to see changes, which is kind of a hassle and makes everything take really long.

I tried unchecking and rechecking “use custom textures”, but doesn’t update anything. am i missing something? is there a hotkey i should know of?
