Renumbering or reordering a model is not always an options for a variety of reasons. Add an option in AutoPIPE to automatically reuse or recycle previously used segment names when generating new segments.

Example:
If after adding segment AC, segment G was deleted. Give the user the option to enable a setting where AutoPIPE would automatically reuse segment G for the next inserted segment. Afterward, the software would continue assigning the next available segment name (e.g., AD) for following segment insertions.
