Undo Grow Selection

[ewerybody]

pew.. I just played a little with selections and .. It looks completely foolish, but that here just does what was simply impossible for me until now:

CODE
{
   string $sel1[] = ls -sl;
   select $sel1;
   GrowPolygonSelectionRegion;
   string $sel2[] = ls -sl;
   select $sel2;
}

It grows selection.. fine, but this you can undo correctly!
I heard that will be standart in Maya 7.
