Is License Scheduler able to provide a recommended license server to user job?

Is License Scheduler able to provide a recommended license server to user job?

We defined two license features in License Scheduler with same feature name. One of them is used for a specified cluster so LOCAL_TO is set for it. But we found that sometimes user's job script check out license from global license servers even if the job request local license.

This causes the non-shared value to fail to be preserved and the preemption will occur.

I understand License Scheduler cannot control which license server user's job script actually check out from. May I ask a requirement that License Scheduler provide a recommended license server for user jobs?

Begin Feature
NAME = vxliese
LM_LICENSE_NAME = Incisive_Enterprise_Simulator
FAST_DISPATCH = N
DYNAMIC=Y
ALLOCATION = default(cr1 1 osrcr1 1)
SERVICE_DOMAINS = vxliesSD
GROUP_DISTRIBUTION = vxlies_group
End Feature

Begin Feature
NAME = vxliese
LM_LICENSE_NAME = Incisive_Enterprise_Simulator
FAST_DISPATCH = N
DYNAMIC=Y
GROUP_DISTRIBUTION = vxlies_group_osr2
ALLOCATION = default(osrcr1 1)
SERVICE_DOMAINS = vxlies_osronlySD
LOCAL_TO = osrcr1 <<<<<<<<<<<<<<<<
End Feature

For example, LS could provide an environment variable to show which license server is recommended to this job.
User submit a job in osrcr1 cluster to request local license "vxliese@osrcr1". If free license of vxliese@osrcr1 is enough, the job will be dispatched. When the job run, job script is possible to checkout globle license server from vxliesSD instead of vxlies_osronlySD. LS Admin would like to prohibit this usage.
LS could set an environment variable that's value is a license server name from service domain vxlies_osronlySD. Job script could read the value of this environment variable. Then job script set the license server name to user's application. Finally, user's job will use local license actually from vxlies_osronlySD.

A recommended license server could direct user job to use correct license actually. It will be really useful to our jobs.
