Multi-treatment feeds allow you to run multiple ad concepts simultaneously within a single catalog. Once you've created your multi-treatment feed, you'll be able to manage all of your designs and treatments.

In order to add a new treatment to assign to its own set of ads, click + New Treatment at the bottom of your Output Feed, name your treatment, and click Create.

This will create a treatment slot for you to add designs and assign to ads.

To rename your treatment, hover over the treatment name of the treatment you want to edit. A pencil and a trash can will appear next to the treatment name. Click the pencil to rename the treatment.

To delete your treatment, click the trash can icon next to the treatment. In order to confirm this deletion, you'll need to click Publish Updates to fully remove it.

Multi-treatment feeds output the added treatments as additional images, leaving the main image (image_link) as the original source feed image. Unless a treatment is assigned to an ad, by default that ad will use the primary image. You can set one of your treatments to run as the main image, so all unassigned catalog ads will use the set Marpipe creative instead.

To set a primary treatment, click on the treatment options to the right and clicking Set as default image

The primary treatment will be marked by a yellow crown next to the treatment name:

You can remove the primary treatment by going to treatment options and clicking Remove from default.
