Trend display question for PI processBook 2015

In PI ProcessBook 2015, I would like to use VBA to copy the current range of a tag (PV) and apply it to another tag(SP) so that when the trend is displayed both tags are on the same range. Any idea ?

 

Background:

The tag on a trend can be selected as Database, Autorange or Absolute. Yet in VBA I can only select Database or Autorange. I would like to know if someone managed to extract the current trended range of a tag and to apply it to another tag. This is paramount when we are displaying PV and SP of a controller and yet adding the output and controller mode to the same display.
