SoapUI Pro 2.0.2

Hello,
Is there an option to tick to eliminate the time accumulated when an error occurs for a test request during a loadtest?

For example, if my loadtest makes a call to a test request 10 times and 2 of those fail, the average result time will include the failures.  I would just like the average calculated on the 8 successes.

If my understanding of the documentation is correct, I read that the time calculations are independent of the running loadtest.  If that is the case I bet it is difficult to corral those errors and not include them in the results...

Thanks for your assistance.
Regards.
