SQTP Puzzle: Write over existing EEPROM without erasure?

Hi,
I am running a batch of a few thousand PIC16F1825 and using SQTP. The EEPROM starts off with values I want to keep, but I need to write a few consecutive bytes of EEPROM over the preexisting data, and no more--the rest of EEPROM needs to remain un-erased.

My question is:
1) How do I use MPLAB IPE to program ONLY those bytes specified in the SQTP .num file, and not erase the rest of the EEPROM? Can you think of how to preserve the majority of EEPROM, while writing over a few bytes of it with the SQTP file? Perhaps it requires a special group of settings to be selected and deselected.

Thanks for any suggestions you might have.
