Prevent Cache on One Directory

[phred]

XYTB 27.90.0019 on Win10

I have lots of photos in lots of directories. I have those directories set to Thumbnails #3 and have enabled "create all thumbnails at once." Is there a way to -not- cache the thumbnails for one directory, but still display the thumbnails?

Thanks.

Thanks. I will add this request to the wishlist.
