SL11 pro loop selection in ARA mode not working

Simple question that I can’t find an answer to in manual or online. Asked Greg online yesterday during his live stream and he sort of confirmed that this function only works in stand alone mode and not in ARA mode.
So my question is: Why is it not mentioned in manuals and why is the function accessible when not working? (or is it a bug?) Just testet with 11.0.20 and it’s not fixed there.
I would love to have it working since I often need it!
