Move group to center of screen

Hi,

So i actually already have a script that works a bit like this. The problem is that it only works for a single object/proxy.

What i would like is to be able to select a group - run the script - and that the group moves to the center of my viewport.

What happens now is that all the object within the group are move to a single point too. I like to maintain the structure of the group.

Hopefully somebody can help me improve the current script.

Thank you.

I noticed that when you select multiple groups/objects, that not all get centered but just one of them. Could this might improved in order to make it work with multiple selected objects/groups?

Thank you :)
