Auto Log Off override by node

Currently, auto log off time is a system setting across all nodes.   Would be beneficial to be able to override this setting on a specific node in POS Settings where other overrides reside.   Often times, bar tablets need to auto log off at 3600 sec so they don't have to log into the software for every transaction, but server tablets need to auto log off at 30 sec so waitstaff don't accidentally ring in orders under the previous employee.   Currently, the work around is to set server roles to AUTO LOG OFF after a transaction, but that requires servers to log back in every time they complete an order and they may be wanting to ring in items for multiple tables while on the tablet.
