[Retros] Coloring + add units?

Speaking of coloring problems, I was wondering if there's any problem so far
that comes with the stipulation of "color the pieces and add the missing
unit(s)"? I know there're a few coloring problems that specify the number of
units to be added, but I couldn't find an example with just "add unit(s)".
At least PDB don't have one under the key words "coloring problem" + "add
pieces". Any idea of this? Thanks :)
