Is there any feature plan to produce DDS ICs with more than one DRG modules?

Digital Ramp Generator (DRG) module is used for generating chirp signal, implemented in DDS ICs like AD9910. Sometimes we need to change DRG parameters e.g. new start/stop frequency. In order to do that we need to use high speed microcontroller to update DRG registers via serial port. Instead of that,  if DDS had more than one DRG modules each programmable independent parameters, we could change profile pins to switch one DRG modules to another very fast. Are there any feature DDS device like that?
