CommoRose binding too sensitive, frequently interrupts ping

Ping and CommoRose are on the same button, and the hold time to activate the CommoRose is so short that I frequently unintentionally activate the CommoRose when I meant to ping. I have to mash the ping button at things to ping them, because of how unreliable the ping button is.

Given how frequently ping is used, the time to hold down the ping button before activating the CommoRose should be at least 400 milliseconds.

I play on PC with a controller, with ping mapped to RB.
