Sub-folders inside collections

Are there any plans to include sub-folders inside custom collections?

1 collection with sub-folders inside:

My Collection
→ Trees
→ Buildings
→ Props

as opposed to 3 different collections:

My Collection Trees
My Collection Buildings
My Collection Props

e.t.c.

Thanks for reading

Keep on keeping on… in 3D : )

This is not planned at this time. Sketchfab for Teams supports this though.
