Adding objects to a selection set: 3) select object on the canvas 4) in the 'Selection sets' dialog, in the list of selection sets, click on the '+' button to the left of the just created selection set
D’oh! I’d tried this but I obviously never managed to click on the ‘+’ as opposed to the text of the selection set (which obviously deselects what you currently have selected). That makes a lot more sense now. Could I perhaps suggest that some sort of hover state for the + symbol (maybe only when there’s an active selection?) might be helpful to indicate that it’s a separate button to be pushed? That seems to be the convention elsewhere in the app as far as I can see. Very happy that I can now maintain selections across layers - thanks guys!
