Campaign builder question

[Hippo]

Is the following possible?  (I'm getting a sinking feeling that the answer is, incredibly, no)

A campaign with multiple stages, with (say) four different missions in each.  As you get to a stage you are assigned a mission at random, if the mission is a success you advance to the next stage where you are assigned a mission at random, but if the mission is not a success you stay in the same stage and have to refly the same mission.

The player never goes back a stage, they have to refly the same mission in a stage until it is completed successfully, they can then move on to the next stage.

I understand that a score of 50 keeps you in the same stage, but I presume one of the four missions would be randomly assigned, which is not what I'm after.

Grateful for any suggestions.  My first impression of this tool is that it is somewhat lacking.
