Custom fields - have the ability to have an abbreviation display in the column heading

We noticed that fields like Priority and Resolution have an abbreviated column heading such as Pr and Res which is great when trying to display lots of columns. Can the custom fields functionality be enhanced to allow the ability to create an abbreviation and have the option to use the abbreviation as the column heading? I did not see any similar tickets to this so I'm creating a new request. If there is one already out there for this, please let me know and I will add a comment/vote on that one.
