Create a +5 mm box around selection

Is there any way to add a square box around my current selection?

I use coreldraw X8 together with Winplot to cut vinyl logos and texts on a Summa plotter and it works great - except I really miss the way I can add those boxes around my selection in Signlab. It's really helpful for stripping the excess film and getting straight edges which helps installing the texts and logos without too much fuss.

I know I can shift click the box tool and it draws a square around my selection, but I need it to make the box 5mm larger than my selection all the way around without having to do it manually. 

I see no default way of doing it, so maybe it is can be done via a macro?

NB: I posted this at the coreldraw subreddit aswell and was encouraged to ask the knowledgeable folks on this forum
