Best practice to map Query tag to OPC tag

I have a query tag that I want to map to a OPC plc tag. I know can map this using scripting or a transaction group. Is this possible to do utilizing reference tags as well? If so what is best practice?
Thanks

Either method will work just as well for a reference tag. I personally prefer transaction groups.

Thank you, going through the transaction groups made it pretty simple to setup.
