Thanks for reaching out to us!
Having the option to use custom descriptions/names is absolutely necessary for a great PingPlotter experience - which is why we've already included it!
To create a custom description, you can right-click any target ( or even a hop within a single trace tab/window ), then hover over the host name and select 'Edit DNS Name'. We have a few more details about this here as well: https://www.pingman.com/kb/article/aliasing-labeling-an-ip-address-23.html
Please let me know if you have any other questions or concerns!
All the best,
