Pauses in telephone numbers on the E61?

I have just been asked a question and wondered if any of you knew if the folowing is possible. For people who need to dial into conference calls and through other work telephone systems a passcode is often required. It can be done on other phones, read on…

“With my old K700i I used to be able to save a number in contacts, complete with the passcode (e.g. 0870 24x 2xxx pin 3xxxx3#) so that when I select the number I didn’t have to input anything else on the keypad. The K700i would input a pause for “tone dialling” by pressing and holding the number 7 but that doesn’t work for Nokia’s.

I just wondered if the same is possible on the E61?”
