High Performance Solenoid Drivers ( redux )

In my previous question High-Performance Solenoid Drivers the MPQ-6615 was recommended as a higher current alternative to the MPQ-6610 used in the article High-Performance Solenoid Drivers | Article | MPS. Looking at the 6615 I see that it does not have an Iset pin. How would I get an equivalent peak/hold function using the 6615?
