Repetitive Data Fields - how to populate them all?

I have one very long form with one submit button. This form has several repetitive fields (example: "billing contact name"). Having my form user have to repetitively enter and re-enter this same data is a nuisance. 

Is there a way to auto-complete so my user only has to enter once?

Please keep in mind my users will be filling out my form over and over full multiple customers i.e. not one time users.

Hi,

I presume that the solution you are after would be shown here: How to Populate Field with a Value from another Field?

Do let us know if that is not what you are after as well as if that was right on the money :)

Best Regards,
Ben
