Xenia-Canary config for d3d12_readback_resolve

I could not find how to configure d3d12_readback_resolve on Xenia Canary and it is needed for some games like Blur otherwise there are missing textures but I could not find a way to set it from inside retrobat advanced config for the game. It is a performance heavy option so it is not recommended in general but it does fix some games that have texture issues. Adding it to the xenia config directly is not something I would like to do. Thanks for any help.

Thanks! Is there by any chance something for mount_scratch?
