PI Point Data Ref. for Rolling Avg. 1 day Ago?

This is probably not a programming question, but more of an AF configuration question.

 

I would like to create a data reference in which I return a smoothed (10 min Avg) of a pi point at one day (or more) in the past.  

 

The goal being to compare yesterday's trend against today's in a processbook display.  I can do this with Datasets in Processbook, and I can do this with PE's in Calculated Tags, but it would save a lot of time if I could do this in a data reference in AF.

 

Am I trying to do too much with the base AF functionality?
