Options dialog for Place from CC Library
Implement a possibility to choose how to import .ai items from Library. Now there is no dialog or options for this at all.
If your item has transparency Indesign uses import setting from last imported .ai object and provides no way to choose this for the current one. So if you want to change it you have to import no-matter-which .ai from local computer -> set desired transparency background option -> import your item from library.
This workaround is absolutely not obvious, thanks for Adobe forums it posted there (from year 2016).
