Hy Gene_Spartan80, yes there is a way to do it, if your truck has the factory turn signal switch, or a good aftermarket switch which takes the output of the brake light switch into the turn signal switch where the brake light signal can be distributed to whichever (or both) brake light filaments are not being flashed to indicate you are making a turn. The factory wiring harness should have been set up that way, do you have a maintenance manual or at least a wiring diagram? Hope that helps.
