Creo 4.0 Mirror Multiple Components With One Command in Assembly

Creo 4.0 Assembly Model Question

PTC was touting their "mirror components" in the assembly mode in Creo 4.0.  I found that Model tab/Component/Mirror.  I did finally figure out how to not have the software create a new part (dumb, why bother?). 

But what I want to do is mirror multiple components in the same command.  I tried grouping components but nothing I found allows me to mirror multiple components in the same command.  (Which saves an enormous amount of time even in simple assemblies.  This is allowed in SolidWorks and Solid Edge!!)

Is there a way to do this in Creo 4.0?
