How to modify multiple items at once

From what I’ve seen so far in the free version, your bulk edit plugin looks very nice. But, I’m not seeing a way to select multiple items to bulk modify. For example, I may want to add a category to multiple items, or append a note to the description of multiple products. It looks like I can only modify one product at a time, and not select multiple products to bulk modify. Does your plugin have the ability for a user to select multiple products and bulk modify them at once? Thanks
