It would be awesome if we could link a IDMS file or be able to add a InDesign file to CC Libraries and be able to place that into another InDesign file. This would be great for reusing pieces of text or layout that occasionally gets updated in multiple documents. When place the IMDS there could be an option to keep the link so if the version in the library is updated so is the placed version or to place a copy that does not stay associated with the one in the Library.

I know it is possible to place inDesign Documents in a InDesign document and a possible work-around would be to save the InDesign File - Place the Placed InDesign file in another file and the add to the Library but it creates a extra step in creation and editing.
