"Open file in..." function missing!!!!

Where is the "open in" function???!!! Cant send files from other App to Pamfax. Have to save them as photo into camera app first, then switch to pamfax, select "open from", search for the correct file and then import. Waste of time!!! Include the function as soon as possible for better rating!!!
