@mbajur @abelio ah, I see. So it seems it is supported, however, I haven't seen one AP service that uses it this way so I'm not sure any would support it natively without having to change code.
However, I'm definitely interested in seeing it and how it interacts, though I'd hate for you to build depending on that, then realize nobody has support for it and then have to re-do it. Though, admittedly, I don't know how hard or easy it would be to re-do after the fact.🤷♂️
