How to manage printed check "Void by Overflow"

Situation: Have 80 invoices, of 10 dollars each to pay to one vendor. The check stub can only print 35 lines. So,  I want to void two pre-printed check stock numbers, use the stub for the 35 lines of detail and then print 10 lines of detail on the third check and the full amount of $800.

Testing: I see there are two ways to set default limits on check format detail. One is at the Bank Account payables document level, the other is at the Payment Process Profile level. I'm using the seeded Oracle "Standard Check Format (Stub After Payment) ". When I set both to the same number, say 35; I get three checks, $350, $350 and $100.  When I set either limit to unlimited, with the other at 35 I get three checks as above with two other checks voided by overflow. Messy and not helpful.
