Sorry, this is a help forum staffed by volunteers - your fellow users. No one here is in any position to make changes to the program. The suggestion was of a potential other way to accomplish what you want.

Ctrl+Shift+Alt+S will give you the Styles Pane

Also, the Styles Group on the Home tab is only styles selected as "Quick Styles." There are far more styles available and potentially in your document than are shown there.
