Conditional formatting in waterfall

Hello!

One quick Q. Is there any way to apply conditional formatting to the total Bar in waterfall?

Like here. I have a negative total and want it to be red. Although another dataset will produce positive trend and in that case i want the total to be green. I.e. follow the general color scheme - red for negative, green for positive.

There is no option for conditional formatting in available color schemes. Guess its not available yet?

Thx!
