Importing objects (fob) from code

Hi all,

I want to write an update routine to import a fob file from within NAV. Is this possible in native c/al without running an external powershell command?
I need to have an easy way for the end user to update an add-on solution to the latest version. The fob will never contain standard NAV objects, just objects in our own add-on range.

Gr, Erik
