I have different shipping rates for different suppliers and it is quite tedious to add products to categories.
Sometimes I need to add thousands of products to a category and the only way to do this (that I have found) is by searching the product names, scrolling through 50 products, waiting for more products to load and repeat. All the while the more products I select the slower they load and my computer feels on the verge of crashing.
It can also be hard to make sure the right products are being allocated to the right group by just searching the titles/ vendor name when there is such a large volume.
Is there a way to just add a collection to a shipping category or create a rule for this in liquid?
