PSA Price Lists (cost and sales)

In PSA I have created both a Sales Price List and a Cost Price list.

But I must be missing a step on how they are linked.

When create a quote line, I am only getting one price.

Should I not get a Sales and a Cost Price?

What do I need to do to get this to happen?

Also not sure if this was posted in the correct spot.

I do not see any categories for PSA.

Hope I am not the only one attempting to use it :)

Thanks
