Allow Filed Label Update while Field is in use

Please create a way for me to update the field label of a field when it is in use! We have fields that we are using throughout our instance that are too deeply integrated to update with the current workflow. Our specific use case is related to attribution tracking. We are adding and changing some UTM fields and would like to update our field labels to denote 'First Touch' and 'Last Touch'. We are using global forms but the fields are still too intimately tangled with our programs, filtering, etc. for us to be able to remove the field from use in order to update the name. Its not critical to the business but it would make my life a whole lot easier if we could do this!
