Thank you for your post.
Currently, there are two ways this can be done.
1. Draw the different wall variations in a SketchUp model (off to the side preferably) then save the model as a template so they will always be there when you draw new models. Then all you need to do is right-click on the desired wall and select '+ WALLS > Create Similar Wall'. This will open the Wall Tool dialog with all the options & values from the selected wall so you can then draw it in your model.
2. Draw the different wall variations and then save them to your SketchUp Component Library. Here is a video which explains how this can be done - https://youtu.be/IXRvzxu-geI
Would you be able to please let me know if this works for you?
