Delete partitions in DSSManagedFolder

Hi,

having an object handler of type dataikuapi.dss.managedfolder.DSSManagedFolder how can I remove all partitions except the last N ones? The dataiku.core.managed_folder.Folder has nice methods list_partitions() and clear_partition(), but this one does not provide.

Should I get the definition of partition scheme, use filePathPattern and list the contents of the folder? I think it's doable, but looking for a shorter/simpler solution

Thanks

T.
