I have created various Styles for documnts I use, and want those Styles to appear in the Quick Style Gallery. I have no trouble adding them to the gallery, and within those documents I have deleted most of the common Styles that I do not use. But when I create new documents, Styles other than those I have created seem to show up unexpectedly.

How do I manage my Styles to always have the same group of Styles appear in the Qucik Style Gallery?
