Update reference tip

Update reference tip

We are new users of CMM manager and so far it is excellent! We just ran into an issue where we have our probe assembly setup with a reference tip calibrated and have been using it successfully but had to add an extension in between the PAA1 module and the TP20 to extend our reach. I am trying to update the new probe assembly with a reference tip but I get an error, it also will not let me delete the reference tip from the old assembly. How do I delete the original reference tip and switch it to the new longer assembly? Any help is appreciated.
