Can I test What-If with multiple bets?

On the Betfair web site I can test the What-If figures in a market with multiple possibilities such as the Football Correct Score that has 19 - 0-0, 0-1, 0-2 etc. So I can place potential bets against several of these score lines to test the What-If figures (and in my case even up the outcomes).

In Market Feeder I can only see a way of testing a single bet for its What-If effect. Is there a way of testing multiple bets before placing them? I include both MF and Time Machine in this.

Thanks, Stephen
