I think you're referring to stock tickers, not stock links. Stock links go on packagers that are connected to your storage. Stock tickers are what you seat mobs or place blaze burners next to for accessing the inventory of all your storage. Use attribute filters (made with brass nuggets and wool blocks) to make categories by placing an item that has the same attributes as other items. For example, if you want to sort all Create components (mechanical drills, harvesters, casings, etc), right click in the air with the attribute filter, place any Create component inside the attribute slot and select the "was added by Create" attribute and click the + icon in the right side. Then, right click the stock ticker and place that filter in an empty category slot and name it what you would like. Now when you click the mob that's the clerk, everything that fits that attribute will be sorted into its own category. There is a possibility that items will have attributes that fit in several categories you created and they will show up in all that apply. Like stone bricks will be sorted into a category you may add for stone types as well as one you may add for anything labeled as bricks. Answer from Dangerous-Quit7821 on reddit.com
