Auto Delete Reports Option for a Task via GMP

Hey everyone,

This community has been epic in helping me! Thank you. I hope I can get another assist.

I have read through the documentation, played with my GMP scripting but am still unable to get the option set in a task for it to automatically delete old reports via GMP Scripting. I would like to set it up so there are only 2 reports on the device at any time.

Is there an undocumented way to do this or am I missing it?
