Request for more save state slots

[Zophar1]

Greetings friends. Just a request to see if it would be possible to raise the number of save state slots on the MiSTer from 4 to 9. I dabble in speedrunning and having an extra few slots would make a big difference in my ability to practice games since I can set more "checkpoints" to practice.

If it's a limitation, I understand. Thanks for your consideration!
