Possible to disable cluster EVC settings on a single virtual guest?

Is it possible to disable the cluster EVC settings on a single virtual guest?

We just enabled an EVC "Westmere" setting on one of our clusters and did the normal virtual guest power off and restart to move them into the EVC enabled cluster.

We have a single virtual guest that within the Windows virtual guest, the application in use, keys pretty specifically to the hardware it's running on and now shows up with licensing disabled.

Our cluster is a mix of two Westmere generation servers and two Sandy Bridge generation servers.   I suspect the virtual guest was running on the Sandy Bridge generation servers and now with the entire cluster running as Westmere, the application detected that as enough of a change to unregister it's license.

Is there any way to change the settings of a single virtual guest to not use the cluster's EVC settings and put an individual CPU masking on the virtual guest of the Sandy Bridge cpu's to run it on the Sandy Bridge hosts and allow that information to pass through?

Perhaps you can use the per-VM masking settings to override what EVC is masking?
