animated text for simulations

I'm wondering if Storyline has an animated text feature for manually adding simulated text into fields in existing simulations? I am creating software simulations and have to alter some of the screen captures to replicate what the system will look like at final release. I have created a mock up of a login screen that requires the user to enter login details into text entry fields. There does not appear to be an animated text feature like Captivate has, to simulate a user entering text. This is a really useful feature as it allows you to edit errors in your captures or change text entry as the client requests after doing all your captures.
