I was tring to post this as an idea, but is not working...
If you have existing components that you need to change the variable name in the File->Properties and DataCard (i.e. variable Shaft Length to Length), you need to open each file and re-map the variable manually.
It would be nice to be able to rename the variable name or to use a replace with an existing one and the varialbe inputs to be automatically connected,
