Interact on controller options

As a controller player I appreciate that I have the option to put a skill on my interact button, but I would really appreciate it if you could add an option that prevents any skill from occupying the same button as interact.
I'm sure plenty of players have mentioned that they've been killed while trying to pick something up because there was a skill linked to their interact button, but my issue is the fact sometimes a skill I don't have assigned (something I only use for bossing for example, or specifically skills that are granted via weapons and items like spellslinger and the abyssal staffs) will get assigned to the interact button whilst changing maps, and I wont notice until it's an issue, usually in a pretty intense situation where I'm being overrun.

Thanks, really enjoying all the work you guys are putting into this.
