When you use the Block command to define new block definitions, and enter a name of an already existing definition, there’s a pop-up giving you the option to overwrite the existing definition.
When you use the new CreateUniqueBlock command however, this option doesn’t exist, and you will be forced to exit out of the command and fix the naming conflict manually.
If possible, it would be a nice little improvement to also include the overwrite option here. Thank you.
