Lightroom "Stacking" Question

Hello,

I have a number of the same shots in lightroom I would like to stack together for viewing purposes. For example, "001.jpg, 001.tiff, 001.jpg_dxo, 001.cr2. 001.dng." These are the same photos, just different formats.

Is there anyway to have lightroom automatically go through 100's of pictures in a collection and stack these similar photos with different extentions on top of each other?

I've tried "Stacking by Capture time" and I would think this would work. However, I can't get it to do anything on the new Beta 2.0 version.

Any advice would be greatly appreciated.

Suspect Beta 2 is not the place to start to experiment as it's probably a bit rocky

there is a setting to stack jpegs with the same name as the raw.. use help in lightroom

Only works if they are in the same folder though
