Patching a Sidewall Rim Leak On The Bead?

So it turns out my rim leak, was not caused by dirt, sand , or gravel, there is an inch long crack in the tire right on the bead under the rim. It was a fast rim leak, tire just went flat. Can this be patched, plugged, rubber cement, or green slimed. I really just need it to hold for a few days. I used a can of fix-a-flat when the flat happened, did nothing. But I didn't know what caused the leak, because it was so fast, thought I ran over something.

Not only is it likely there is more structural damage than just what appears on the outside, that particular area is carefully dimensioned to fit the rim in a certain way - so the tire seals properly. There is almost no way to get that dimensioning correct, short of remolding the tire.
