SaveAs PBM

Question

Hello.
I need to save my current active document as a PBM format file via CS6 javascript.
However, I'm running into the problem that there's no PBMSaveOptions object defined that I can pass into the saveAs function.
My output always gets converted to .psd even if I define a .pbm extension.
Anyone know if I need to create a custom Options object or another trick?
Bottom line: there don't seem to be enough SaveOptions objects to cover all the formats Photoshop can save to via the GUI.
The Javascript reference lists these:
BMPSaveOptions
DCS1_SaveOptions
DCS2_SaveOptions
EPSSaveOptions
GIFSaveOptions
JPEGSaveOptions
PDFSaveOptions
PhotoshopSaveOptions
PICTFileSaveOptions
PICTResourceSaveOptions
PixarSaveOptions
PNGSaveOptions
RawSaveOptions
SGIRGBSaveOptions
TargaSaveOptions
TiffSaveOptions
Thanks for any help.

Thanks for the idea.
Yes. I did try that.
The problem I run into there is getting the filename of the current document changed to save to the correct file.
I can alter the path (C:\\Users\\len\\Desktop), but not the filename, by analyzing the generated script code (below).
Here's what it output:
var idsave = charIDToTypeID( "save" );
    var desc2 = new ActionDescriptor();
    var idAs = charIDToTypeID( "As  " );
    desc2.putString( idAs, """Portable Bit Map""" );
    var idIn = charIDToTypeID( "In  " );
    desc2.putPath( idIn, new File( "C:\\Users\\len\\Desktop" ) );
    var idDocI = charIDToTypeID( "DocI" );
    desc2.putInteger( idDocI, 37 );
    var idCpy = charIDToTypeID( "Cpy " );
    desc2.putBoolean( idCpy, true );
    var idsaveStage = stringIDToTypeID( "saveStage" );
    var idsaveStageType = stringIDToTypeID( "saveStageType" );
    var idsaveBegin = stringIDToTypeID( "saveBegin" );
    desc2.putEnumerated( idsaveStage, idsaveStageType, idsaveBegin );
executeAction( idsave, desc2, DialogModes.NO );
