Power Chart disallow editing of tag path

On a gateway with multiple tag providers (especially remote tag providers), I feel that the Power Chart should have the option to enable/disable editing of the tag path (while still leaving editing of other things like axis, color, name…etc. Having access to the tag path could prove a security risk if someone is clever enough to modify it with a valid database name, remote gateway name, tag provider name, and tag name. They could end up viewing data from a completely different tag provider.
