Setting isolated sketch visibility (while in another sketch)

Greetings

I'd like to make a single sketch visible in a part file. Currently using SW 2012.

I can set visibility to show all sketches at once,  hide individual sketches,  and show individual sketches that were previously hidden (with visibility, sketches, active).

I'd like to select a single sketch in the feature manager and show only it - while inside of another sketch.

Thanks in advance for any insight.
