Hi Julie,
Sorry it is kind of an odd situation. One of the guys I work with is creating a schedule and he wants to have different shifts for different days. The only way I could think to do this without creating seperate tasks was by putting the shifts in the resource columns.

For example:
theres a task that takes 10 days but the first 2 days there are 2 shifts of workers and the next 2 days there is 1 shift etc...

Not sure if this clears it up at all but I am very new to Project so thank you for all your help!
Katy
