Describe the feature
Allow items to be dragged from JEI to the pattern terminal to create recipes and allow numbers to be set. Could work similar to Just Enough Calculations mod.

Reasons why it should be considered
Some recipes work better when used in multiples, like 1 bucket might make 4 of something. This would prevent having to run through the whole craft step by step to get a final pattern.

Additional Context

The items shown in JEI quite often have additional or missing data compared to the crafted ones. Due to the way minecraft/forge handles items, for us these are completely different items and you could compare it to define a pattern to craft a furnace while it's actually a chest.
