Multi Edit lets you apply the same change to multiple assets at the same time. For example, you could use Multi Edit to:
Add products to the Clearance category on a weekly basis.
Activate a New Color flag for a newly-added group of shoe SKUs and deactivate the flag for older SKUs.
Add the phrase “New for Fall!” to the beginning of the long description for a list of products.
You can use Multi Edit with catalog assets, promotion folders, promotions, coupons, content assets, and media assets. You cannot use Multi Edit with price lists, sites, site groups, or targeting and segmentation assets.
