Support for Availability Groups in multisubnet environments?

We are running DPA version 9.0.146 and are successfully monitoring an availability group listener publishing a single IP. However, our preference would be to connect to a listener publishing multiple IPs on different subnets. When trying to register the instance for monitoring in DPA using the multisubnet listener the initial step fails usually with a login timeout.

I see the Microsoft JDBC driver for SQL Server v 4.0 supports the multisubnetfailover connection attribute but I'm not sure what DPA is using under the hood for connecting to SQL Server. Is this something that is not supported, available in a later version or is there a workaround?

Thanks.
