[Plugin: WordPress SEO by Yoast] Add tag for page parent title

Hi,

could you please add tag to display page parent title?
something like %%pageparenttitle%%

I’ve installed Ninja Page Categories and Tags plugin to add category and tags to page (that should be a built-in feautre in wp btw).

However I have these pages
Discography (category: discography)
-Album
–album1
–album2
-Singles
–single1
…

Initially I had set these tags for Page’s title template:
%%category%% – %%title%% – %%sitename%%

But when I’m in ‘Category’ page
The title is of course: “Discography – Discography”
It works fine for the very first child page “Discography – Album” ’cause it takes page’s category.

However when I’m on an album page it looks like “Discography – album1” instead of “Discography – Album – album1”

So, adding %%pageparenttitle%% would fix it. Thanks.
