Lightroom mobile: Any plans to handle hierarchal collections in mobile / web

Hello

Are any plans to handle hierarchal collections in lr mobile / web?

I just started to used lr mobile and web including synchronizing collections. It runs smooths and is very useful.
But I miss the possibility of have collection sets in collections sets which I use a lot in my local lightroom, otherwise it will quickly become difficult to keep a structure and overview.

Best regards

Torben
