Refine Mask _ Mask Type_select

Its a small thing, I hope, to ask, but can a select mask type be added when opening the Refine Mask please? Instead of the "display mask" text , please replace it with "Choose Mask Type " and have a tick box for regular Mask, or Grayscale Mask, alternatively default, on opening, to "Grayscale Mask and add a tick box to change over to the regular Mask
