Ability to see edit button in reports

Ability to see edit button in reports

I have some techs I gave access to reports to that want to run some of the canned reports... however the edit button does not appear for them (to be able to change filters etc for their reports and dates etc)... I went into their role that they are assiggned to and gave that role full control over reports, but the edit button still does not appear.
 
We are using 8003 version.  Any thoughts on how we can get that button to apear without making them an admin over the whole system... what other groups can we put them in.....
