Directories – last modified

Hello!
This fantastic plugin saved our school’s ass in corona crisis – we use it for the pupils’ work sheets in the different classes and subjects.
It’s a lot we uploaded – so I decided to create directories for the subjects.
Everything works fine except: there is no “last modified” for the directories, so the pupils can’t see if there are new work sheets for them (for example in maths) – so they have to open every directory first and search.

Is it possible to add this feature – so we can sort the directories after “last modified” and see the modification?

Thank you!
