I don't think so, not in the way you'd like, anyway. It might be possible, might, to make universal default for corner rounding. Probably have to create a template file to save that setting. The problem would be, every corner would receive the rounding. Doubt that's a desired attribute. I've never tried to do that, so, don't even know if possible.
The other option might be to make a custom stencil which have shapes with already preset rounding...these could be 1-D shapes too, I think. Then, just drag and drop whatever shape is desired. That should give various, preset roundings, which could still be adjusted once on the drawing page.
