Sadly, no.
I understand it seems overwhelming, but 50 planets really isn't that bad.
While TA has less planets than DA, even TA can have over 500 in Gigantic or Immense. Imagine having to overbuild on all of those...or even, say, 90%.
For what it's worth, I'm fairly positive it would require significant enough coding to not make it into the "small" updates that are planned at some point...but it couldn't hurt to make it a full-fledged feature request, either; it'd be incredibly useful.
