is it possible to open multiple URLs in app mode via command line?

[G B]

I use raspberry pi's for kiosks at my job.  i run chromium in --kiosk mode and am able to open multiple urls tabbed without an issue.  the problem is that one of the sites we use has a function that opens a new window which exposes the "View site information" button when clicked shows cert info, cookies, and the Site Settings button which takes you to chrome://settings.  When i add the --app="url" switch the settings menu is hidden but i need to open multiple urls with that switch and if i add two --app="url" switches only one of them gets used.

this is my string: chromium-browser --kiosk --disable-cache --disable-infobars --touch-events=enabled --disable-pinch --noerrdialogs --disable-session-crashed-bubble --app=URL1 --app=URL2. 

As these are kiosks that the public use i need to lock them down as tight as possible.  I don't know if this is a bug or not but it looks like --kiosk isnt consistent.
