Softimage :: How To Select Rotoscope Images And Remove Them From Explorer

I have a quick question about how rotoscopes work in Softimage.

Basically, when I set a rotoscope image in a front viewport, for example, and I set another viewport to act as a front viewport, the rotoscope options aren't synchonized, which means I can set more than one rotoscope image for the same viewport. This gets a little confusing sometimes because I'll be unable to remove rotoscope images from the viewports because I forgot which one I originally set them in.

Is there any way to select rotoscope images and remove them from the Explorer more easily or anything like that, without having to remember the exact viewport and corresponding orientation in which they were originally set?
