Is it possible to change the aggregate start time on trend charts? For example, I want to overlay the shift average for a tag on a trend chart that displays the the time average of the tag throughout the shift. However, the our shifts run from 6AM-6PM and the 12 hour aggregate runs from 12AM-12PM.

I thought about using a value box to just display the shift aggregate value, but the tag I am using in the trend chart is calculated from multiple tags and I didn't see a way to do that calculation with the value box. If there's a way to do this I'd be curious to know too.
