Can we offline an entire folder of files through the mobile app?

Perhaps I'm the only one using the Offline files function but I'm surprised that one has received much attention over the years.

I use this function a lot (on the iOS app) and would like if it could reflect the folder structure of the cloud-based storage.

I often refer to files I have made available for offline use, for instance because I am travelling internationally and don't have access to wifi. This is difficult to do in a user-friendly way in a very very long list of files. 

A normal file browser type of interface would be the best. With larger phone screens this should be possible to fit in.

If Dropbox could also simplify the "make available offline" function, it would be ahead of the iCloud Drive which really doesn't let users save files for offline use in a simple way. For instance a long press on a file or folder could bring up a simple menu with save for offline use, in addition to things like move or copy.

Thanks for considering
