Another Repeater question (Foot controllers)

[Scott Winzinger <zing@sigecom.net>]

I heard about the Digitech 3 button foot controller but how can I get a
foot controller that will allow me to also be able to have an undo
button as well as a seperate loop 2 button.

Is there such a foot controller as  a say  5 button:

Record, Stop, Undo, Loop A , Loop B,

I'm a solo acoustic guitar player and would like these functions to be
accessed by my feet.
