Or how about (wait, do something else for a few seconds, and then as the landing crosses the threshold)
"Fastair345 line up."
(Or if there's a possibility of confusion)
"Fastair345 line up runway##"
(Or if a takeoff clearance will not be issued pdq)
"Fastair 345 line up (runway##) and wait (reason)"
Or you could just go the full monty and use 3+ transmissions and dozens of words instead.
That certainly has a place, if you need to manage the timing of your r/t, for sure. But just because conditional clearances are available, doesn't mean you have to use them.
(Know a guy who used the first method on a check, one time, just after they'd been brought in. He couldn't remember the correct phraseology. Passed the check.)
