Speaking with a Housekeeping Supervisor, they'll use departure reports out of SAM to prioritise RR or EC cleans where the room has been vacated in last 48 hours, and will pick these in ACA Workloading to keep on today's run.
If there was the ability to expand the Sort by drop-down that currently exists, to include an option to filter and group by would be helpful.
This would allow them to filter to those clean types and then sort by departure date or arrival date.
