different tab leader for table of contents

Hi

i've created a table of contents for a document, but i don't like the tab leaders there are - you only have a choice of dots, dashes, solid line, or nothing.
Is there any way to get different tab leader style?? - what i'd like is a dot style, but with the dots more spread out. Is this possible?
I'm using word 2007 if that makes a difference...

thanks for your help!:smile:
