We can route multiple records at a time from queue view.
I guess you are talking about sub-grid controls box when you show the view on dashboard.
To get the Queue associated view along with controls on dashboard, you can create a web resource and show it on dashboard so that you can use Route button to assign multiple records at a time from Dashboard.
Note: I am passing Queue id as parameter to webresouce i.e. QId=DBAF1512-6659-E011-A421-001E0BCA0A54
also you can use it for other entities if you set parameter for oType i.e. entity type and tabSet i.e. relationship name
