I would like to be able to enter phone numbers in the Calendar that fully support the format options to use embedded pause(p) and wait(t) within the numbers.

I have many bridgelines that are of this format that I dial into:

123-456-7890.... wait for announcement ... enter 1 digit number... wait for tone ... enter "*" followed by 6-8 digits and then "*" again.

Some are less complex but you get the idea. I would like to be able to put them in like this:


And have the t's properly wait for some user input and the *243543254* not try to start a new phone call. Today if I try this it dials the 10 digit number and then if I hit the *3453425* it tries to dial a second number and nothing good comes of it.
