I wouldn't do that. I'd give you the descent and speed too.
In the first circumstance I'd say "make speed not above 250 knots below ten thousand feet, descend and maintain 5000 feet."
In the second, "make speed not above 220 knots below five thousand feet, descend and maintain 3000 feet".
If you choose to level off to get the reduction, that's your choice.
But I'd probably choose a distance base point; OM, joining final, fix on the route distance from touch etc.
Of course we understand that it's hard to wash off speed and descend; but it's you decision to comply or not, if not shout.
