delete Rev Table macro

At my company, we reuse a lot of parts as the start for a new part and deleting the rev table is getting tedious.  Can anyone point me towards a macro that will blast the old rev table, reset the drawing next rev to A, and insert a new rev table with an "initial release" rev "-"?  Since I doubt there is going to be one that's exactly like I want, Even pointing me to parts woudl be helpful.  Thanks in advance.
