Edit the <title>-tag

Hi,


I'm looking for a way to edit (expand) the contents within my <title>-tag.


Currently under Theme Options - Configure SEO - Meta Title Tag format I have the setting "Page Title - Blog Title". In the General Options I have set Blog Title to "MyNiftyBlogTitle" so when looking at the source of a page it says:

<title>CurrentPageTitle - MyNiftyBlogTitle</title>


Is it possible to edit this setting to produce:

<title>CurrentPageTitle - MyNiftyBlogTitle - ExtraTextSimilarToSlogan</title>

I want the ExtraTextSimilarToSlogan to show up all over the site, so adding it on the Atahualpa Post Options at post.php won't really do it.

(And if I add the extra text to the Blog Title in the general options, the whole shebang shows up in the header area on every page.)


It's really a clarification to the <title>-tag in order to make myself and hopefully Google happy. Is it a SEO-plugin I need?


Thanks,

Bo
