Two new menu entries for Items and Variants have been introduced to the Web UI to increase the efficiency when working with a multi-tier product paradigm.

Assign to product/variant : This functionality allows selecting one or multiple items/variants and choosing a parent product for them all in one go. In the case of an already existing assignment, it can be chosen to move the item/variant to the new product.
Generate product/variant : This functionality allows the generation of a parent product/variant based on one selected item or variant. Similar to the functionality in the Desktop UI relevant fields will be copied to the product/variant as well.

These menu entries are available in the Master catalog and for items as well as variants. The behavior and permission of these actions are similar to the functionality known within the Desktop UI already.
