Hi Miquel
I'm so sorry for the late reply - I simply didn't see your question.
The "Save As" menu option can be edited using the
Menu Designer which is available from the top menu "Windows".
In the Menu Designer:-
- click the edit box with "File" text - it has number 1
- next click "Save As" from the listbox ojn the left
- next click the "Edit Script" button and it will open up the editor
- next add a call script or make a call to your script in the Main Code section
Here is an earlier post on menus that might help
