You may want to elaborate on your needs, what you are asking makes no sense.
Let me try to understand...you want to add a manual lever onto your steering column to shift your manual transmission?
You have a non-tiptronic automatic car and you want tiptronic buttons on your steering wheel?
Both are doable but as most people will tell you is probably not worth the time and money involved.
But yes. Wires exist that will shift the gears up and down. You can add whatever kind of switch you want. Toggle switches on the dashboard, even.
*Theoretically* you could even repurpose your headlight "Flash" switch and your windshield "washer jet" switch and make the car shift gears up or down when you pull back on those stalks. That would be crazy, but anything is possible.
