I have an issue with a script that places multiple page PDF files...

Question

I'm using a version of "PlaceMultipagePDF.jsx" that I modified to use Media Box when placing the PDF file pages.
That part was easy and works perfectly.
The issue I'm having it that every time it places a PDF page, InDesign pops up a dialog saying that it's Importing pages from "file" and Creating preview with a progress bar. This dialog pops up once for each page, and the UI time it takes to do this is slowing down the import.
So is there any way to turn off this feedback dialog?
Note: I still need to see the dialogs to choose the PDF file and pick the document and page to start placing. I just want the one that displays for each page to not display...

I found this in the Developer KB.
But I can't find any of the functions in the Scripting Ref...
How To: Suppress the progress bar when processing a command.
Summary
You can suppress progress bar display by turning it off before processing the command.
Issue
I use the IImportFileCmdData interface and pass kSuppressUI (do not display any UI) as UIFlags. When processing the command, I get a progress bar, which is called "Adobe InDesign Tagged Text Import Filter", whereas I expect no UI.
Solution
To suppress progress bars you should explicitly turn them off before you process the command (or commands).
1. Get the interface IProgressBarManager (it's on kAppBoss, which you can get from gSession).
2. Use IProgressBarManager::SuppressProgressBarDisplay() to turn off the progress bars.
3 .Process the place command(s).
4. Turn the progress bars back on when you're done.
In InDesign 2.x and above, you can also use the SuppressProgressBarDisplay class (ProgressBar.h) class to achieve this. In order to use this class you just need to create an instance of the class on the stack as shown here:
SuppressProgressBarDisplay suppress(kFalse);
