Scaling and moving objects after multiple imports

[Tbird]

I need to import my model in separate imports as different objects.  They all import fine in size and orientation to each other, but I can't figure out a way to scale of the objects together after the fact. Is there a way to regroup them so that the whole scene can scale together?

Go into the scene tree tab of the options menu, multi-select the models that you want to scale, then right click and select "scale".
