I don't know that you'll damage anything - though if you're shifting the front under full load, you'll probably increase your chances of throwing the chain and potentially do some damage that way - but the long and short of it is: don't.
You don't need to sit down or stop pedaling completely or anything - you just need to practice letting up for a half second while you shift.
