More than 1 pause in extra digits in phone #

I call quite a few numbers that require dialing extra digits for voice boxes etc. Creating a pause between numbers is a fairly easy task to complete on my Centro. What I cannot figure out is how to create 2 pauses? When I check my own work voicemail, I need one pause to dial my box number and 1 pause to dial my password. Is that possible? It was a simple task on my Razr.
