BLO.BlockReplaceBlock

Replaces the entire Nth block (with delimiters).

 

Intention

 

This command targets the Nth top-level block in a string and replaces the entire block—including its start and end delimiters—with a new string. This is useful for substituting a complete element in a list with something else entirely.
