How to seperate shadow catcher completely

Hey - I was wondering if it's possible to completely cut out the shadow catcher and have it render separately. In Cycles there is a hold out option to remove an object completely, then you would have the shadow on a different pass. How can I do something similar here? The goal is to composite the final shadow in photoshop. Pro Render doesn't seem to have a hold-out option.

I can use the shadow as a selection and cut it out in Photoshop, but that doesn't seem like the right solution.

I've included a picture of my project, if I need to upload my .blend I can but it is big. The frame backing is the shadow catcher.

Add an "RPR Passthrough" shader to the object and set it to the color (0,0,0,0).  Well any color really with the last value (alpha) being 0
