Allow the editing of groups of tools when creating large assemblies that share custom properties.
Example: A hold down assembly requiring a HD, nut, washer, threaded rod, and epoxy are specified in detail "1/S101." The detail currently has to be typed into each custom property field for each tool. Being able to apply "1/S101" to all relevant tools at once would save a considerable amount of time when creating assemblies.
Batch editing can currently be done via the markups list, but is cumbersome and error prone for large groups of different parts.
