Actually it's not an unwarranted assumption. This significant failing goes back years with numerous correspondents on other Affinity forums also asking for something to be done about it but thus far remains ignored. I don't want to faff about with work-arounds, just a simple keyboard action. It's no good Serif trying to be a creditable competitor to a giant like Photoshop when they seem little disposed to sorting out such a minor issue. I want to draw multiple circular marques accurately from the centre of maybe up to a dozen layers with each getting progressively smaller in diameter on each layer. Quick and easy to do in Photoshop but impossible in Affinity Photo. Like I said previously, back to PS.
