Bike fit for road and tri? same time?

Help: I just bought a Jamis Xenith 57’ bike. I would like to set it up to be ridden for both road and tri at same time. Can this be done? I read somewhere that jammer (short) tri bars can make this happen. I can’t find where i read this but would like to know what to do before i get fit. I would like to do it right the first time. Thanks to all.
