[HD/Texturing] BTNRallyPoint.blp with different team colors

[Barade]

I want the texture "ReplaceableTextures\CommandButtons\BTNRallyPoint.blp" in the team colors from 1-8 or maybe all team colors. This would help me to use it as hero icon since I could distinguish between the different rally points of different players. Another flag symbol would be fine, too as long as it has the team color.

I tool would be great where I select a certain color in an icon and it will be replaced by all team colors and generates icons with the different team colors.

I guess I will have to create different unit types for the different icons since I cannot change the hero icon of an existing unit?
