Exterior trims don't have matching swatches

I've been wondering if it's possible to custom edit exterior trims so I can have some matching colors for the trims in builds. There's several that don't have a dark wood option. If they could all have matching wood tones that would be awesome and make builds so much better. I've attached a picture with all the trims that don't match. They have pairs that match each other, but none that can be used together with other trims. Like the "Jutting Exterior Trim" can be used with the "Inlaid Exterior Trim" but nothing else. These are all base game trims and it would be INCREDIBLE if the team could edit the swatches so there's matching wood toned trims (if there could be a matching dark wood tone and a light wood tone for each trim, that would be amazing). If not, just tell me how I can custom edit them and I'll do it myself.
