MarketPress - digital downloads, price per licence?

Hi there,

My client will be selling digital courses. The user will need to choose how many 'licences' they need.

The cost of the digital download will depend on the number of licences they choose (there is only one digital download).

Morever there is a quantity discount structure also:

1 - 5 licences will cost £40 per licence (e..g 5 licences will cost £200)
6 - 10 licences will cost £30 per licence (e.g. 10 licences will cost £300)
11+ licences will cost £20 per licence (e..g 20 licences will cost £400)

Is this something MarketPress can do? If not, is there some workaround to this?

Many thanks
