I need to draw a round hole on a polygon pour.

I've followed this documentation (see video in "Subtracting Selected Polygon Pours" paragraph). It explains that you must first selected the reference polygon and then all the polygons you want to "remove" from the reference polygon.

My concern is that I can't select the other polygons while they are fully inside the reference polygon. If I click using the shift key. It deselect the reference polygon...

How to do that?

Edit: I need to remove the highlighted circle from the disk but not the other copper region:

Starting from this: enter image description here

to this: enter image description here

Hold shift and left click on all the polygons, then let go of shift and right click on the poly you want the others to subtract from. The right click should give you a list where you can select (with left click) the subtract command.

OK, here's what I did:

Convert center circle to polygon pour, put it in the right position in polygon manager, repour, convert big disk to free primitive, delete center disk. This must be done when everything is done because, repouring cannot be done anymore on the big disk. enter image description here
