Garage Door Opener

I recently bought a used 2000 Silverado extended cab. The garage door opener in the overhead console is just a door to put my remote in. Since I have more than 1 garage door, this doesn't really work for me. I am wondering if I can purchase the 3 button system like I have in my '99 K1500 Suburban. If so, what's involved in installing it?

woops, some how I managed to post twice.....ignore this

I saw this modification on a web site. Look at www.anythingcars.com/members/chane/ it shows the over head consloe that will support three garage door openers.
