Modify "Rows per Box" settings for all users


I have search through the archive and cannot seem to find an answer for
how to set a default “rows per box” setting to all users I want to set
it to 50 and not the default of 10.

I know you can do this individually for each user in the “Customise RT
at a Glance” section, however I have not given my users the "ModifySelf"
right and don’t want to have to give them this right so they can do

Is there anyway to set the “rows per box” setting globally?
