Can you change the shader save path?

Hi

Is it possible to change the directory for where all the shaders are saved? I know by default they’re saved in C:\Users\Name\AppData\Local\UnrealEngine. However, my C drive is running low on space, and it was already taking up around 15GB of space! I’ve moved the folder elsewhere, but when I loaded up an old project, it continued to save the shaders to the default path. :-\ I’ve even changed the Local and Shared Derived Data Cache folders under Edit > Editor Preferences > Global, but it doesn’t appear to be making any difference.

Thanks
