Minecraft automatic crate system?

I wanted to ask if such an automatic storage system can also be built in such a way that, for example, 2 items are sorted into a box, because it is very annoying to have to use a box for each individual item.

Could you maybe link something or just say if it works at all?

That should work if you use the same as for a 1 item system only that you use two different items.

It is possible to simply build the same thing behind it, i.e. The same design as before. Should go, you can then drive over the Hopper Minecarts and below they come in the box

I think it could mess up the machine if you let two items flow through a "conveyor belt", so you would probably have to build two different lines per box.

Nope, it doesn't work that way.

Called itself "Multi Item Sorter". Just enter on YouTube and you will find many designs.

Concepts for multi-item sorters:

Possibility 1: Simply build several 1-item filters and let them flow into the same box.

Option 2: Pre-fill each slot in the box with a desired item and then e.g. Use the following design. Disadvantage: You always have to have 1 item in each slot. :

Option 3: Designs with multiple filters:

I would recommend option 3, because you can sort many different items into a box, and there are no disadvantages.
