Hi @Key123 , you can do this in a few ways. I will give you 2 of them, and you can even apply both, depending of your actual background requirement.
1- You could create a new SASApp Application server and indicate that all what goes in that Application server will go to an specific queue, or even certain nodes only.
2- You can create a SAS Grid Options set, on which you determine the combination of Application Server (could be the default SASApp) and the client application, would go to a queue: https://documentation.sas.com/doc/en/bicdc/9.4/gridref/p1p4pemn1rt2hyn1pim235u2s012.htm
This is done on the SAS Management Console/metadata.
