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.
