coldfusion flash integration: Is there a way to disable a <cfinput required /> field with actionscript?

Here's my scenario - I have a flash form with several tabs. Each tab page has
various form fields and a submit button. If the user picks tab #3 and fills
out its form fields then hits that submit button, they get an alert saying that
the required fields from tabs #1 and #2 need to be filled out. I don't care
about those if the user is submitting tab #3.

Can I write actionscript that will cancel the "required" attributes of the tab
#1 and #2 fields when tab #3's submit button is hit?

One workaround would be to not use the "required" attribute at all and write
my own AS validation. However, I like the built-in functionality of the red
highlights for required fields and the email, and url validation. Does anyone
have any other suggestions as to how I could do this?
