How to limit linked text

Hi all,

I'm trying to link part materials to a drawing template, and was wondering if I could limit the length of text or number of characters that are displayed in the area that I am designating for this parameter?  For instance if I choose or create a plastic with allot of characteristics included in the title, I would like to limit the name to perhaps the first 15 letters, then in a separate area of the drawing if needed, I will place the full name of the material.  I would like to do this so that a linked part material will not spill over into other areas of my title block.  I would also be interested in a method to create 2 lines if the length of text is too long also.
