11: When creating a customer, can I change the "First name" and "Last name" to just be "Customer"? If so, how would I do this?
Ok. Here goes. This may be a tad long, but it works. If it can be done easier, then please tell me.

. It would take too long to write it all out, so it's just in simple txt format. Sorry.
