IPad /iPhone app HC+ / dimmer levels

I just finished a 153 device two mst. job with 10 shades...working beautifully I might add in 8.0. The question is why can't the iDevice / android adjust the levels and "save " on the actual dimmer. Example : I set the dimmer to come on to 75% on each button press ( adv settings) on the physical 6NA dimmer in programming via inclusive. The client can't change thru iDevice to set each time it's physically pressed to go to 50% .The client is bummed about this... He can change the scene thru a keypad programming and press "save" but not at the dimmer location. Please correct this in the new app update.
