@oneruffryder, just helping out a bit in the spirit of open source. I'm in no way a form of official support nor am I affiliated with Yoast.
And no, I don't do requests - unless someone is paying me for it.
I'd seen the topic you point to before and haven't got a solution at the moment - would need a lot more studying of the code than I'm willing to put in atm -, so I have nothing to contribute to it.
Sorry.
