Park Macros

It doesn't seem possible to create a proper Park Macro. Learning a Macro, I open Park, Put Some Channels in it, close park and go back to live. Learn another one to remove those channels from Park. Playing back you'll see that the console goes crazy, often unparking every thing in Park. Editing the Park macro often has disastrous results. I tried removing some commands out of the macro, like RESET_CMD or whatever, and the other one in there that said preview something. Playing it back obviously doesn't work, but now it puts the console into an odd state where pushing Park once on the console will open the park view right away (instead of double pushing park). Only an Exit will save the desk and bring it back to normal.
