temporary breakpoint

Is there a way to set a temporary breakpoint using a debug command, similar to the "Go To Line" right-click menu option? I'd like to set breakpoints via the BreakSet debug command that only break program execution once. I'm trying to get the breakpoint to delete itself; I can execute the BreakDelete function as part of the breakpoint command but the command doesn't know the current breakpoint number. Any other method to do this?

Thanks,
Robert
