GPT partition, motorola.update_gpt, custom recovery.

Hello XDA,
I wanted to know if anyone knows about this "partition" or porting the proprietary command motorola.update_gpt to TWRP.
I know we can flash the gpt.bin via fastboot I know it is more than one actual partition from the output fastboot gives.
I know rsd lite or rsd can flash this as well with filename="gpt.bin" operation="flash" partition="partition"/> from the flashfile.xml contents. This gives me less info to go on as it calls the partition "partition".
When looking into the device I get the list of partitions by name and get no partition called "partition".
