I'm not Altos, but I might be able to answer this for him: Yes, there is one, though it is spread across many sources over a couple years, so it is hard to keep track of.
Back in early 2020, when only Debbie, Amy Rachel and Cassandra had punishment systems implemented in part, it was decided that the twins, Faye, Alice, Zoe, Priti and Liz would get punishment systems of their own as well.
More than a year later, in May 2021 (just after 0.10 came out) there was a vote on the order for these new girls. 0.11 had already been earmarked for Cassandra, but after that the list was Priti in 0.12, Faye in 0.13, the twins in 0.14, Liz in 0.15, and Alice in 0.16. Of course, cast offs from 0.12 have since turned into two whole updates, so you have to add two to all of the build numbers.

I vaguely remember reading that Zoe (the student antagonist, pictured above) was supposed to get her system implemented in 0.17 - now 0.19 - and that it was supposed to be the conclusion to 'Chapter 2', but I cannot find that anywhere in writing, so take that with a grain of salt.
There is also an unanswered question if Altos is going to add any other new girls to get systems of their own after all of these have been implement in part or in whole, or if the 'roster' for the game is now closed. However, to my knowledge, this is the most complete map we have of development at this time.
