Clear command-queue macro command?

I've looked around a bit, but was unable to verify; when writing macros, does a command exist that clears the current macro queue?

It would be nice to be able to include a line at the beginning of a chain macro, that would clear any previously queued commands, in case the first ability in the previously queued chain had missed, and you didn't want to have to wait to cast the whole chain again? Otherwise, maintaining DPS is a bit hit and miss on higher-end mobs...

If this doesn't exist, can I request such a thing, please?

Looking like that's a negative then. Quick example of what I was after, as a request then;

/clearqueue
/ac "True Thrust" <t>
/wait 2.5
/ac "Vorpal Thrust" <t>
/wait 2.5
/ac "Full Thrust" <t>

etc. That way if True or Vorpal don't land, pressing the button again will reset the queue and start the chain fresh, to maintain optimal DPS.
