I believe for VSE you can only assign 1 policy per system tree node, not like IPS Rules where you can have multiple policy instances.
But you could:
1. Put your exclusions for SQL and Backup Exec in the same policy and apply it to the system tree nodes needed.
2. This requires a bit more work but, go to your On-Access Default Processes Policies, and choose "Configure different scanning policies for high-risk, low-risk, and default processes". See screenshot. But then you need to configure the High/Low policy along with the Default. But you could specify exclusions for SQL in High, Backup Exec in Low, or something like that.

I put all the exclusions in 1 policy and applied it successfully, but I like suggestion no. 2 as it is a bit more organised.
Thanks for your help, very much appreciated
No, that is not possible.
