Set tiered pricing levels in Conjoint

Hi all,

I am building a conjoint module but our products have tiered pricing (i.e. You pay less per user as you number of users increase). So what i want to do is ask a pre-question for how many users the person will need and then only display the relevant price per user in the conjoint. I have 6 price levels per tier so i don't think i can use conditional pricing. From what i can see i can't use display logic either so a little stumped?
