There are a few quirks when creating tags in UDT definitions.

1. Pasting tag JSON into a UDT Definition in the Tag **Browser** (_not_ editor) returns this error:  
`Exception: Error importing tags: Only Udt definitions can be imported into the UDT Definitions tab.`
2. Pasting tag JSON into a UDT Definition in the Tag **Editor** doesn’t do anything - no errors, no tags created, just 2 steps closer to developing RSI 🙂
3. Pasting copied tags from the Tag Browser into a UDT Definition in the Tag Editor does nothing. See (2).
4. To paste tag JSON into a UDT Definition, you have to:  
a. Paste the tag JSON into Tags  
b. Copy the new tags  
c. Paste the tags into the UDT Definition in the Tag **Browser** (not editor, see (3))

It’s almost like you need a cheat sheet to tell you what you can do when and where 🙄  
What I would like to be able to do is to paste tag JSON into the UDT Definition in the tag editor _and_ into a UDT Definition in the tag browser to add new tags.
