STEVAL-BMS114TX wiring for unmounted cells

Hello everyone,

My apologies if this is in the wrong forum. I have a STEVAL-BMS114TX evaluation board and I'm wondering what to do with unmounted cells, since my pack is 5s. 

The datasheet for the L99BM114 says to short the unused PCB connectors together, but this definitely cannot be done on its corresponding evaluation board. 

Does anybody have any advice on how to move forward with this? The STEVAL-BMS114TX datasheet says that it can manage from 4 to 14 battery cells, but doesn't provide much clarity on unmounted cells.

Thank you for the help.

Essentially, this is the same question that should have been answered here already by @Max VIZZINI.
