pca9952 for 7 segment display

Can I turn the segments on and off using the LED driver output state registry 02h through 05h and the brightness commands will remain constant? 

I need to control the brightness of all the segments and to go from daylight to night readable I need more than 14 bits of dimming. The 9952 Looks like I can do this using both the individual and group dimming.

I only need to command the brightness when I update the display brightness which is fairly rare, but I need to send new values to the 7 segment display many times a second. so I would like a simple quick way to send an on off command to the driver per segment but have it remember what brightness it was using last time.
