The users. subdomain of Smogon was depreciated a long time ago.
Programmers who are willing to put their free time doing unpaid contributions to the Smogon and Showdown codebase are inherently uncommon, and they focus on things they prefer to do or find important. It's likely that there are tool out there of some sort to do similar, or even just some basic Excel/Google Sheets formulas or a user-maintained PS Bot. I seem to recall a bot that has a .bulk command - Scrappie maybe?
But the short answer is that - something being coded requires someone to code it. If you're interested to take up the challenge, there is the
Technical Projects subforum you can take a look at.
