I have a backup database that I would like to use to query tag history from using the standard `system.tag.queryHistory` function.. however it seems as though the function is tied directly to the history config on the tags themselves. e.g. if a tag's history provider is set to A, I can't tell the function to query from B instead.

Is the only option to replicate this function myself? 💀

Use QualifiedPath objects instead of TagPath objects in your lists.

Of course! I was testing with the Vision EasyChart which doesn't have a GUI for choosing the history provider like the Perspective Power Chart does and it corrupted my thoughts.
