New TinyMCE - Add blockquote with cite and/or title

I have recently upgraded a TinyMce editor in an Epi site from v 1.0.0 to 2.8.0. The old TinyMce editor had a button for the editors with the functionality to add a blockquote-element with the ability to add a cite- and/or title-attribute to the blockquote element.

This was an Episerver plugin to TinyMce with the name EPiQuote, is this plugin no longer available? Can't find any useful information.
