Branding Satellite

Hi,

We have multiple satellite servers and sadly, they all look alike!

Does anybody know if there is a way to change the look of a Satellite server so we can easily identify which is which, in a way that would not be erased when we update or upgrade?

I know there's something in foreman such as:
https://github.com/ShimShtein/foreman_themify
&
https://github.com/jcmcken/foreman_custom_banner

Can either of them be applied to Satellite?
