is it possible to scale elements to a specific size?

Hi there,
Im trying to create an overview page for my PLC (Siemens logo!).
So i downloaded the dxf files of the devices im using and used the dxf to element plugin.
After creating the new elements I saw that they were too small. Now I am wondering if there is a way to make an element a specific size (not just eyeballing it with the green dots in the editor).
I need them to be the same size because I also need some extension modules for the logo.
I could make the Logo CPU + extension module in one element, but then I would need a new element for each configuration.
