To achieve what you are requesting you need to use Totalizer Tags. In PI SMT, you need to user the Totalizers Plugin, not Point Builder. It is there you get to set the source tag to anything in the PI Data Archive to feed the Totalizer.
If you were to keep record of total Watt Hours of, for example a transformer at a production site, this is what you use.
Thank you Karl! That is very helpful!
