Please help; Stereo 3D Sync / DNG Sequences

Please help. I'm trying to setup a workflow for a S3D project in Studio 17 on Mac.
The shots come in DNG image sequences 4112x3008 and are placed in clip folders and then in Left and Right folders.
I can't stereo 3D sync the DNGs, but it works fine with mov. and R3D footage.
Does anyone knows if 3D sync works with DNG image sequences?
The only way to import them as S3D is to click each shot individually for left and right folder.
Thanks,
Sebastian
