filtering based on folders as taxonomy

Dear all,

is there a way to make a folder structure available as filters (like a tagging taxonomy) in views, like the table view?

We have big amounts of user stories in a backlog, which are all "tagged" (taxonomy) with "folders" and we want to make those accessible through filters and sorting. However, I can't get our folder structure (taxonomy) to show up as filters or in any way useful way in those views.

My initial idea was to feed the taxonomy structure dynamically into a custom field. However, creating the tags additionally in a custom field is not feasible as doing this manually is a lot of work and error-prone.

Any help with this is very much appreciated.

All the best
Hannes
