An equipable cart to carry more stacks of the same item

Can there be a equipable cart to allow the player to carry more than one stack of the same item?
Cause its hard when your farming a certain block then to move those to a different world you can only carry one max stack of 999. or even just moving it aroud that world and organizing it is pretty tiring.

So im thinking of a pixel cart sort of item, a second inventory of somesort but can carry more than one 999 stack of items.
Of course it should still be an item that needs to be upgraded to have more inventory space and maybe a limit to carrying only farmable blocks.

The devs want to move away from block farming. Here is a thread explaining a little more about why:
