Please add an Attribution Model Selector to the Doubleclick standard report connector definition.  Here is Google's description of the selector:

"Choose an attribution model to use for this report (created in advertiser's Floodlight configuration). If no attribution model is chosen, then the Floodlight attribution model is used by default."

We use the attribution model selector primarily to to pull reports using Google's Data Driven Attribution model, but it can be used for any custom attribution model defined by the user.  If an attribution model is selected, the connector can probably be used by only one advertiser/account at a time.
