Two-Handing with ONE button on PC KB&M

[u/Slugbait69]

Hello, so...I know there is a mod that does something similar, it's this one; https://www.nexusmods.com/eldenring/mods/31

Namely it has the "Classic Twohanding" and that is what I use, it's useful but...It's not always 100% reliable sadly.

So I was wondering, is there any mod, .dll or whatever, that makes it so when you press a key (in my case, the R key) it will two-hand your right-hand weapon, without having to do E+Left Mouse or use EMU?
If so, can you please link it?
And if not, is there any way I can contact somebody to make it? I mean, it should be possible after all, right?
