Modifying ''Copy'' behavior

Hello! I''ve noticed that there is good support for customizing the behavior of the copy operation in the grid, except for just a few small, but critical, things. For example, I can''t seem to skip hidden rows or columns. Ideally, I would love to be able to handle the CopyTextToBuffer(...) operation of the GridModelTextDataExchange class, since there a some other small tweaks I''d like to do in there. Right now, I have to duplicate the code of five methods in the GridModelCutPaste and GridModelTextDataExchange classes when I really only need to modify the CopyTextToBuffer method. Any suggestions or would it be possible to fire a new event in the future? Thanks, Terry
