Auto rename fields

[Caitlin__]

When the name of a field is changed early in a workflow, all corresponding tools that use the renamed field should have the option to auto update the field name. This way I don't have to manully update the name of each effected field.

This would be a game changer! Would save me so much time!

Definitely would be a big help!

This would be super useful!!!

The fact that this isn't a standard feature is frankly mind boggling

Can't believe no one has thought of this sooner!
