I wanted to do the same thing.
There was a related post with Timeline:

here's how to do it:
1) create a new page in your pages builder. Enter the Page URI and Page Title.
2) log into phpMyadmin (or whatever mysql program you host utilizes)
3) find "sys_page_compose" table in your database.
4) find: "_wall_pc_view_index_ol" in the caption field.
5) click on "copy" and then look for "Page varchar(255)" field and in the value section, replace "index" and type in the PAGE URI (like "my_outline_page" or "whatever_you_just_named_your_page" in the pages builder for that page).
6) click GO (save).
7) go back to your pages builder, refresh your browser, and Outline should now appear as an inactive block for your page.
