Saving MRQ render outside project directory

Looking into the Cinematic Assembly Tools as well as the traditional {format_strings} for a way to automate a new project’s save location.

The production pipeline accesses rendered frames from a folder outside of the Unreal project directory, like:

X:/Studio/Project/Renders

Whereas, Unreal is located in:

X:/Studio/Project/Unreal

Maybe there is a way to tell MRQ to back out of the Unreal project a few levels and save to the comp/edit accessible location?

It doesn’t look like CAT addresses this need. The closest I can find with MRQ is the {project_dir}. In theory it could be something as simple as a few {../} followed by the /Render/ folder address.

Any ideas? Or are we fated to save within the Unreal project directory?
