Displaying Quick Tags as horizontally cascading columns

Pressing Enter displays the tags available at the cursor location. For me, a long "tall" list appears. For certain tag locations, this list extends well beyond the vertical limit of my monitor. Is there a way to show this Quick Tags list as a horizontally cascading group of columns so it goes "across" my screen (as shown below)?  I'm using Arbortext Editor/Styler 6.1. Thanks!
