Is it our minhag to make Shlissel Challah?
There is no official Chabad minhag as such. But it’s perfectly ok to make the shlissel challah, and the minhag is based on holy sources.
If there is a design on the challah, even if carved out from the dough itself it is proper to be stringent not to eat and break it on Shabbos. However, if the entire challah is the shape of a design one may eat it.
