Can I subtotal in the bill?

[schirallicpa]

Trying to manipulate the master form so my billing makes better sense and is easier for the assistant working up front meeting people.  Would like to subtotal the cost of the tax return and then add on the other admin fees or 8821 fees (if they opt for it) so that that I don't need a separate bill for that.  And so the person helping me isn't having to stop and do math to back it back out.  (Just because this is an accounting office doesn't mean anyone who helps out lately has any basic math skills.)
