Customize Controls Problem

[rose rover]

I started the game and wanted to change some controls. I am an OG AC player and wanted to set my sprint to hold R2, then I saw my binding got inflicted with heavy attack, so like in AC Mirage I wanted to set my heavy attack to “Hold R1” except that option is sadly not possible. Is there any way you guys could look into that and maybe make that option possible? It would mean a lot to me and I also think many others! If you can, thanks in advance! 😁
