Hi, thanks for providing the link, so its technically possible to add that but its quite a bit of work, so, unless a lot of users requests it its probably not going to be added, also i usually do not add non standard stuff to Kustom so its also a matter of being "clean".
However in Kustom its possible to write plugins and this would be a very good scenario for that, someone could write a small app that just feeds Kustom with this information.
