When you transfer a Counterparty Asset, you send a dust-amount of BTC as well.

Is it possible to transfer any amount (>= dust limit) of BTC in a Counterparty transaction?

For example, an electronics store sells a TV for 1 BTC. However, if you have a discount token, you'll get the TV for 0.9 BTC + 1 discount token. Can the 0.9 BTC + token be transferred in one transaction?
