Library "Place Copy" feature mirrors InDesign "Place Item(s)", retains page X, Y coordinates
Generally, when items are placed in an InDesign library, they retain the page coordinates of their absolute location on the page. Sadly the CC Library doesn't retain this information (it's only drag and drop), which forces designers to spend a lot of time precisely aligning elements when that feature could be automated.
1) Allow the assignment of a master template to library items. I noticed that all items added to a CC Library (when edited directly from the library) access a generic letter-sized InDesign document. Would it be possible to point instead to a specific base template that matches our custom page size, styles, baseline grid, color palette, etc.?
2) Let us use the Description field (or a custom field) where we can input an X and Y coordinate that the Paste in Place feature takes advantage of?
3) Some other custom control or additional command that allows an InDesign element to retain its X, Y positioning information -OR- the designer can drag the item out, but it loses its X, Y positioning, just like with current InDesign libraries.
If all that fails, would there be a way to centrally manage InDesign Libraries that individuals can download manually and be notified when there are updates?

You can play a copy of the static element by Alt-Click + dragging the element to the canvas or by right-click and "Place a Copy"

Well, with a bit of playing around it turns out the fine folks at Adobe already took this into consideration. It's a bit hidden, but after you drag an item from your library and onto the page and your cursor turns into the green plus icon DON'T CLICK! Instead, hold down the option/alt key THEN click. The object should remember its positioning from when it was placed into the library and pop into the correct location.
Personally, I would still prefer a right-click Paste in Place option directly in the CC Library so I don't have to drag it onto the page (letting me place multiple items from the CC Library at the same time) but that's a quibble at this point.
Thanks for retaining this (albeit hidden) functionality, Adobe developers!
