increase / decrease dosing base on ph value read in

can I program the profilux 4 doser's dosing amount to change base on ph value read ? for example, if the current dose is at 5ml, if upon reading ph is low, have it increase dosing by 1ml, to 6ml ? and keep 6ml as the new dosing amount for subsquent dosing, until the next ph reading increases or decreases it again ?

thanks.
