This doesn' t help you now, but Slurm 20.11 is expected to have "magnetic reservations," which are reservations that will adopt jobs that don't specify a reservation but otherwise meet the restrictions of the reservation:

If you want to apply different limits inside and outside the reservation, you'll need to setup different QOSes for inside and outside the reservation. One way to do this in a way that is transparent to the users is to use the job_submit.lua script to check if the reservation has been requested, and set the QOS based on that. Prentice
