No, it is not. SmartFade ML has only one 'colour mix' controller per device, thus multiple sets of RGB can't be controlled. For this reason, such 'multi-cell' fixtures are specifically excluded from the personality database.
The preferred solution is to patch each cell as a separate device, as you then have all the usual controls - including a 'virtual' Intensity for each individual cell.
If this isn't possible, then you can build a User Personality to put the extra cells onto the other parameters that you find most suitable.
