enter it as text in the description is probably the best answer, e.g.

tie yellow ribbon around old oak, 2nd Jan
chase noisy cat away at 1am! 5 Jan, plus $1 for late call out

Why ?  Invoice dates (and their separate lines if splits are not 
accumulated) are significant in tax and accounting terms so the account 
(as opposed to the printed invoice) must reflect the actual tax point 
(or whatever it is called in your jurisdiction).

The other way is to invoice each job separately and then produce a 
statement (customer report in gnc parlance) as a request for payment, I 
will leave it up to you to decide on retrospective invoicing and your 
tax regime but the general advice is don't.
