[Help] How To Set up the "Cost model" into CPV in Voluum

Hello,

I think that the title is self explanatory, I would like to run a PPV campaign with Voluum and to calculate the ROI, Costs.... you should specify if its a CPC, CPA or CPM campaign, there is any way to setting up this option with CPV and calculating all costs accordingly?
The traffic source I'm using is 7search

Many thanks in advance.
