[slurm-users] Beginner admin question: Prioritization within a partition based on time limit

I'm just learning about slurm. I understand that different different partitions can be prioritized separately, and can have different max time limits. I was wondering whether or not there was a way to have a finer-grained prioritization based on the time limit specified by a job, within a single partition. Or perhaps this is already happening by default? Would the backfill scheduler be best for this?
