P: Automatically Discard 1:1 Previews: Would like additional options beyond 30 days

I would like to see a few addtional options on when to discard the 1:1 preview data, such as 90 or 120 days.

I have a very large LR Catalog (1.85+ million images) which is currently housed on a 15 TB U.2 SSD locally on my desktop. Right now I have about 4 TB of free space on that drive but am looking ahead to when I will run out of disk space on that drive and options are limited on for getting a larger SSD.

In my particular case I mainly touch photos throughout the school year, for various newspapers and/or schools, but once the school year is over I don't go back to those photos very often, and usually would only be working on a single or smaller number of photos which would minimize the pain to rebuild them if I did go back to them.

Alternatively, if there is a way that I can identify the "age" of the preview files I would not be opposed to a tool to do that, or the information that would allow me to create a script to remove files that were beyond a year old (for example.)
