Keeping document positions of InDesign CC library items after editing them

At my job, we use InDesign libraries very successfully to hold groups of elements, including dated text, that must fall into specific locations every time they're placed onto a document. Using the place option in the library's contextual menu, this works like a charm. We also edit these grouped library items annually by placing the items onto a document, updating their dates, highlighting them, then right-clicking on the library items and choosing update library item. We are now in the process of developing a new workflow utilizing Adobe CC, and I've been testing whether the CC Libraries feature will be beneficial to us. I have discovered that library items can be edited by double-clicking them or choosing edit from the contextual menu, but I am not seeing a way that allows them to retain their initial document positions (x and y); this is critical to our workflow. Is there a way this can be done? If not, we have no problem continuing to use the regular InDesign libraries as we always have.
