preempt queue on derecho

Data assimilation jobs (using DART and CESM) could benefit from using the preempt queue on Derecho.
The assimilation cycles can be made to be < 10 minutes long, so there is a natural stopping point
within the PBS request...kill window.
I don't see 'preempt' in CIME as of cime5.8.47, so I'm wondering whether there's been any discussion
about how CESM might use this queue.

If not, I'll work on implementing it within the DATA_ASSIMILATION_SCRIPT.

My thoughts around the preempt queue was to trigger a cesm restart write alarm in esmf. This is a feature request that we have submitted to the esmf development team. I think that implementing this in the DATA_ASSIMILATION_SCRIPT for dart would be appropriate since that would be a natural break point for that case. Maybe you would like to meet in person and brain storm this idea a bit?
