All in one seo plugin adding meta titles for geo directory fields

I am having all in one seo packs, and I want to have geo-directory contact field in meta title. The only options I am getting to add are :
%blog_title% – Your blog title
%blog_description% – Your blog description
%post_title% – The original title of the post.
%tax_gd_place_tags% – This post’s associated Place Tags taxonomy title
%tax_gd_placecategory% – This post’s associated Place Categories taxonomy title
%post_author_login% – This post’s author’ login
%post_author_nicename% – This post’s author’ nicename
%post_author_firstname% – This post’s author’ first name (capitalized)
%post_author_lastname% – This post’s author’ last name (capitalized)
%current_date% – The current date (localized)
%post_date% – The date the post was published (localized)
%post_year% – The year the post was published (localized)
%post_month% – The month the post was published (localized)

Can any one help me to get the custom code, so that i can get the contact fields in meta title.
