Hi @codynew
Currently, I don’t have a solution for this, but I wonder if google may reveal someones code which could help you achieve the filter.
ACF uses the exact same javascript uploader as WordPress, so if someone has written about a solution, you will most likely be able to integrate it with ACF
If you do find a solution, it would be great if you could link us to it to help future readers
Sorry I can’t be of much help on this one.
Thanks
E
