Guess, fill in blanks/complete a row with a color by long pressing that color

[Chemicthyologist]

While playing the beginnings of guess (most efficiently) one fills in all the possibilities with a color. There is a feature to carry over previous colors into the next guess (heh) pattern, could there also be a way to "fill in all remaining blanks" with a color by holding down on that color from the color selection panel?

Thanks!
