Dual bump buttons on sub masters

I've been using EOS now for 4 years busking lights for live bands and DJ's and have love using the console but I would love to be able to have dual bump buttons on fader strip allowing you to have either 2 flash buttons but one with a fade time or one flash button and one hold button, this would allow users to busk a show much easier then having to add extra fader wings or external midi controllers.
