bq40z60: template or guidance for programming the Registers section

I have recently switched over to using a bq40z60 in my design.  I have been reading through the the EVM users guide (sluub71) in addition to the Technical reference manual (sluua04d) in an attempt to figure out how to program all the correct register sections for a 4 serial 2 parallel battery pack using NCR18650B cells.  In some of the previous gauges I have used (such as the bq20z65), the programming software (BQ20Z65-R1_BQEVSW-SW) had had a guided set up (BQEASY) for the user.  The guided set up allowed you to enter in values such as pack configuration, pack capacity, pack voltages, pack discharge limits, etc.   The software would then make sure all the correct register values were programmed for the initial entries.  This guided set up made it very quick for initial setup to get the system working.

Is there a similar guided set up for the BatteryManagementStudio software that i'm using with the bq40z60?   If not, is there some type of template, or example available for which registers need to be set for the type of pack i have?   I have been reading through the Technical reference manual for ba40z60, but having to set each register value individually,  i'm afraid I may miss one, or get something configured incorrectly causing much frustration in just trying to get the chip up and running correctly.

Thanks

    We do not have a configuration tool such as the bqEasy plugin. Fortunately, most of the parameters in the bq40z60 are cell based, so most parameters can be left at their default values. There are a few exceptions and the bq40z60EVM User's Guide provides a Quick Start guide section to help.  You can use our online GPCCHEM tool to help to find a good ChemID match for you cells.
