Can page names be relocated?

My documents contain 40-120 pages, with page names of from 5 to 25 characters  Because space for display of page names is limited, scrolling to reach the desired page is tedious.  Is there a way to relocate page names so they appear in a vertically so that a larger quantity of names could be displayed without scrolling?  Using X6

Would like to do this:
this page
that paggggggggggggggggge
Johns page
that page
that paggggggggggggggggge
that paggggggggggggggggge
Smith page
this page
Barrys paggggggggggggggggge
that page
that page
that paggggggggggggggggge
that paggggggggggggggggge
that page

rather than this: pagggggge   that paggggggggggggggggge  that page  this paggggggggge  that paggggggge  that pgggggggage  that paggggggggggggggggge
