Spoiler:
welcome back. So I will give you some tips, maybe we will find the right solution.
First of all, on the Layout Editor, there is an anchor for the whole warband thing.

Here are some images that depicts the setup (maybe it will work for you too):
1. right click on the Enemy Button:

2. select configuration and select the drop down point "Unit Frames"

3. This point will be a bit tricky. These settings are for my wb layout (like in the first picture). Maybe you have to test which spacing fits for you.
