You can edit multiple assets at a time using the bulk editing menu. To edit multiple assets at once, just select the ones you want to edit with the checkbox on the left side of the asset table. If you want to apply the change to all assets in the search, select "apply to all assets" otherwise selecting all will only apply to those on your current page.
At the top right of the table, you’ll see our bulk editor. For assets, you can set their priority score, add and remove tags, assign an owner and mark them inactive or active.
