Illustrator Help

Hi guys.

I am fairly new to Illustrator and have a quick question;

In Photoshop I could type out a text, and add a stroke to it, then I could render it and add a seperate stroke. Almost as if it saves the text as it is and starts again.

Now in Illustrator, I have a text that I have made slightly bolder by adding the same colour stroke. Now I want to save the text as it is and add a stroke on top of the stroke - the same feature that Photoshop offers fairly easily I cannot figure out in Illustrator.

Any help much appreciated, thanks in advance!
