@ZTR88 I am sorry for the delay in answering. I have been waiting for confirmation from the developers. Annotation which are part of takeoff preferences, which are stored per user/application, eg. in files in this folder:

C:\Users\USERNAME\AppData\Local\Autodesk\Fabrication 2019\APP (eg. CAMduct/ESTmep).

There is currently no way to alter this behavior other than using an external tool to sync those files (you must note that they will not be reloaded unless you restart the application).
