Assign an object/group to an artboard for auto animate
If I want to use auto animate to have an object/group move onto the screen from off of it (or vice versa), I have to group it with an invisible object that stays on the screen so that XD knows the object/group is a part of that artboard when it is off-screen. I could be totally missing a way around this but I can't find anything about it online. If there was a way to assign an object to an artboard even if it isn't touching said artboard, that would fix this problem.
Essentially this makes adding new animations a massive pain because if you want something to move off the screen at some point, you must add an invisible shape to every instance of the object or else it flickers on the artboard you add it.
