Data: can't run data feed to fill in cl conv column unless 'client provides conversion data checked'

There is often a need to test a data feed once it gets to production before

switching tracking methods. Right now, there is no way to do that. You need to

switch on 'client provides conversion data' which means that the data feed is

live and effecting conversions/Admax. What I would like to see is the ability to

specify which tracking method to use explicitly while having data available for

all in the coluumns currently existing - wp conv, se conv, cl conv.
