Way to have Chrome / Firefox open two tabs on startup?

[pdwyer]

I want to push a policy or something out to our computers that when they start either Chrome or Firefox it will open two tabs by default. I found a plist command that will open our home page, but can't figure out where or how to have it open the 2nd tab. My plist is below...

I got this to open our school home page via this plist. Is there a way to open two tabs when chrome is started? I tried below info but no luck, if anyone has accomplished this, please share what I might be missing or did wrong.
