Ability to select the inclusion traits while building a Look Alike model

Hi Adobe,

It will be very helpful if there is a feature to select the traits we would like to include from third party data sets in marketplace while building a LAL model. Current features only allow to exclude the traits with a maximum of 500 trait exclusion. With thousands of traits in each dataset, it makes it extremely difficult to arrive at the traits we are interested to use, by using exclusion method. Also it will be nice if we can see the total count of traits selected while building the model for additional validations.

Thanks
