Currently, managers must navigate between 2 screens to manage agent market assignments because Command Center is capped at viewing 50 agents per page. Managers need to view/manage all agents on 1 page.
#Customer Service
The 50 records per page limit in the Command Center / Shift Manager view is a standard platform pagination ceiling within Salesforce Workforce Engagement / Service Cloud. Unfortunately, the page size dropdown (10, 25, 50) is hardcoded into the component layout, so there isn't an administrative setting or metadata toggle available to increase that threshold past 50.
If your managers need to view and reassign all 60 agents in a single interface without toggling pages, the best workaround is to build a filtered custom list view or report on the underlying Service Resource or Shift Assignment object, where standard list views support up to 200 records per page. You could post this on the Salesforce IdeaExchange to request extending the pagination limit for future releases.
