Table Group By Heading

Is it possible to change the heading that is displayed when Grouping records?

I have a table of Transactions that contains a checkbox field.  My default report is set to Group By the checkbox.  So all checked items are together and all unchecked items are together.  Works great, but the Heading for each section is the value of the checkbox.  Thus the unchecked items heading is "no" and the checked items heading is "yes".

Is there anyway to change the "no" and "yes" to something with a bit more meaning?

Thanks
