resize items in a group at once?



hi, I have a question. 

I have a group with three items: 

An image, a logo and a button. I can easily move all items at once using <left> and <top> as expected.

However, I would also like to change the size of the entire group. Basically make the image, the logo and the button bigger (or smaller) at the same ratio. 

Is that possible?

Very much appreciated!
