From the left navigation bar, select
[Engage] → Content → Ads
On the All assets screen, locate the asset you want to edit.
Hover over the asset and select Update.
In the Promotional Details section, make the following adjustments:
Under Seasonal, apply a seasonal period to the asset from the
[Drop-down menu].
Under Additional Promotional Options, select the

Select Save.
