Prompt for a new file name on first save

Question

I’m creating a form with 15 pages. The user might want to fill out the form several times with different content. So I’m looking for a solution where the user is asked to give a new name when s/he saves the PDF file for the first time. So the original empty form is still available for the next case.
In Word I would create a template, so a document created based on this template has no name unless the user specifies one. I.e. when the user clicks on the save button for the first time s/he gets a Save as dialog.
In Adobe I did not find a similar thing. I tried to add a preSave event asking the user whether s/he wants to give a new name, however then the user will be asked each time to give a name, not only the first time. Maybe I could check the filename, however I wonder whether there is an easier solution.
Any help is greatly appreciated.

Why don you keep a control info in a hidden text field?
I have modified you code a little. (see the lines in red color)
If still not working, post your form to this forum to have a look at it.

ServiceProcurementNotice::docReady - (JavaScript, client)
var   
myDoc = event.target;
var saveFlag = true;
try
var userSave;
if(saveFlag)
     userSave = xfa.host.messageBox("Do you want to save changes to " + myDoc.documentFileName,"Save",2,3);
 if ( userSave == 3 ) 
app.execMenuItem("SaveAs");
saveFlag = false;
txtHiddenSaveFlag.rawValue = "false";       // If you want to keep this info even after closing the form
else
}catch
 (err){app.alert("Exception in save: "+err);} 
 if ( userSave == 3 ) 
app.execMenuItem("SaveAs");
saveFlag = false;
txtHiddenSaveFlag.rawValue = "false";       // If you want to keep this info even after closing the form
else
}catch
 (err){app.alert("Exception in save: "+err);}
