The alignment checks are for your tires relative to each other -- they'll make sure both tires are pointing the same direction at the same time. They don't check whether your steering wheel is aligned, so you're out of luck there.
However, it seems that it's not too hard to tell when the steering wheel is off center. if you'd like, you can take a picture of what the steering wheel looked like relative to the dash before you take it off, then try one notch over to see how different it looks.
This is a steering wheel (on a Volvo XC90) in the proper orientation:

And this is one just one notch off.

These are screengrabs from this YouTube tutorial, which seems to walk you through the whole process if you'd like to take a look.
