A more positive equivalent of "relegate"

In scientific literature, I sometimes see expression of this form:

We consider results 1, 2, and 3 here, while results 4 and 5 are relegated to Appendix Z.

The notion of "relegating" some results to the appendix has a mildly negative connotation in my view, as if results 4 and 5 are so insignificant that one does not want to present them together with the main results. However, there can be a multitude of reasons for placing some parts of the work in the appendix, for instance due to lack of space or because one wants to provide additional details about certain topics of interest. Is there a more positive expression that can replace "relegated" in the sentence above?

It is certainly possible to circumvent the problem by rephrasing (e.g. "Refer to Appendix Z for additional results…"), but I am specifically looking for a word or expression which has a close meaning to "relegate" but without the negative connotation. I was not able to find such an expression with dictionary searches.
