Camera Raw - Export to Subfolder

From the Camera Raw export dialog, I’d love to be able to save directly to a subfolder within the image’s original directory. Currently, the only two options are to Save in Current Location or Save in New Location, which defaults to whatever folder was last used for that option. 

When using “Save in New Location,” if you’re not using that old folder from a previous export, it’s not very convenient to have to sift through folders yet again just to set an export folder. 

What I’m envisioning is the same or similar treatment as in Lightroom Classic in which a subfolder can be both created and selected. The apps’ teams seem more than capable of doing this as-is, and I’d simply like to see it added to ACR for quick work.
