Ford IDS and calibration files

hi guys
Anyone who have install IDS with calibration files know that the latest calibration disk is c81 which is a bit quite old..

Now , my question is :

Is there any way to get the latest calibration file other than going through FMP software?

the dealers must get it through IDS

Does the software download them on its own ?
I assume this require a valid IDS registration ?

thanks for the info.
