Post From: Price/Study Overlay study question

Try this: it will combine the data from two studies.

I made it to use the open of study#1, and the "fill blank" data from study#2. This is the choice in "auto mode"; but if you choose "N= non auto select" in the settings; then you can combine your two overlays which each have different settings.

It might work for you?... It will try to use the data from study #1. If that data array is empty then it will take the data from study #2. For sure you must "fill blanks" on your second input study.

See picture below about study #1 & study #2.
