The Behavioral Triggers Content Block for Emails are great tool for easy Drag & Drop creation of Abandoned Cart/Browse communication, but it is missing one powerful feature. Ability to personalize the email with customer data.
It is already available in form of Einstein User Attributes that can be passed through "setUserInfo" data layer.
What is more, it is also already available in the request that is used in the backend of the current Behavioral Triggers Content Block, by just adding "&user_attributes=attributeName" to the end of the trigger request.
However, as it is neither added by default nor can be configured in the UI of the Content Block, to get this data in the email, one must create yet another, same call with the above query parameter added, which is of course neither user friendly nor optimal (HTTP.GET doubling).
It would be awesome to automatically pass all configured User Attributes to the request and make them available by creating an AMPScript variable with the response, so that we can use it in the email and its subject.
