Placement of circle from a corner

Hello fellow Lightburnians, I have a question that I have been trying to answer for some time by myself and whilst I have a work around it becomes annoying having to do it this way all the time.

If I am doing a wall sign and that wall sign is for example 1230mm by 820mm with 10mm rounded corners and the client wants 10.5mm mounting holes on each corner exactly 25mm in and down on the top two corners and 25mm in and up from the bottom 2 corners my question is this - is there a quick and easy way to place them there or do I have to attach them to each corner of the rectangle and then use those coordinates of x+25mm and y-25mm and do the other 3 respectively. Please tell me there’s an easier way.
