ok, can't i just add a line under company (in customer details) and entitle it License number/State ?

I mean, if i knew what file it was in, couldnt i just copy and paste the company line, paste it directly below that and replace the word "company" with License number/State?

if so...where would that file be located exactly? Hm..maybe developers tool kit could help me find it?

there has to be a simple way for someone with my limited knowledge, right?
