Can I set up the Support Debugging Tool to use the same debugger.xml file for all workstations?
Yes, in fact this is the recommended configuration as it allows settings to be shared across the entire system. Using the workstation you have settings you want to be shared, use the Dex.ini Settings window (Tools >> Support Debugging Tool >> Options >> Dex.ini Settings >> Debug Tab) to change the Pathname location for Debugger Setup files, exports and logs: to a specified folder in a shared location available to all workstations. If there is no debugger.xml file at the target location, the current workstation’s settings will be copied across. Repeat this change on all other workstations. Note: You can also manually edit the MBS_Debug_Path Dex.ini setting.
