Unfortunately the software doesn't support heads up tourneys. You can create a "2 max", but it is not a shootout format; if you bust the other player then you will be paired up with another player who has busted someone else.
It is possible to create a heads up tournament, but it involved manually allocating tables and someone co-ordinating everyone, and chances are it will be played out over a number of days.
