UV symmetry?

I use to finish it (sometimes I make a backup first), but before I use Tools->Virtual Mirror->Freeze I unwrape the mesh. Just after that I freeze it and then on AutoUV window I cut the half segments and flip them to get the unfolded mesh symmetrical.

Here is a gif showing what I'm talking about:
