Thanks for reaching out!
The idea of an "auto-expire" feature is not something that has been on our roadmap, however, I will log this feature request in our system for you.
That said, one thing you may find useful in saving resources and keeping your targets clean I suggest checking out our Data Pruning Script
. Using the data pruning script you can use Windows Task Scheduler to automatically prune any data older than the amount of time you select.
If you have any other feature requests let us know, we would love to hear them!
