Help with Flash File Design

[TechSupp]

Trying to help my daughter who is pulling her hair out with it (and it has to be in Flash as its for a school project, she's using Flash Pro CS4), she wants to create a game where she dresses a male doll on one page or dresses a female doll on another. Now looked at it and she initially said she wanted to use two scenes, one for each but all I have read on the net advises against that for various reasons. Does she create two separate flash files and load each when needed from a third menu flash file (and how do you do that?) or is there a better way to do it keeping it all in one flash file?
