You can use indirection to configure the tag history binding to point to a set of tags based on any parameter on the screen.

In the Property Editor, go to the Data property, and click the binding icon.
The Property Binding window is displayed. -
Select the Tag History option.

From Available Historical Tags, find the desired historical tags by selecting and expanding the historical providers.

Once you have found the tag, drag it into to the right into Selected Historical Tags.
