Arbitrary container I/O

[Foreck1]

I would like to request the ability to define any compatible forge item storage/fluid tank block as a valid input or output for machines.
For example, instead of having to use input bus blocks, defining a specific block in the structure as an input.
For example

{
    "x": 1,
    "y": -2,
    "z": 1,
    "elements": [
        "minecraft:chest@0",
    ],
    "io": "input",
    "type": "item"
},
{
    "x": 0,
    "y": -3,
    "z": 1,
    "elements": [
        "pyrotech:stash@1",
    ],
    "io": "input",
    "type": "item"
},
{
    "x": 0,
    "y": -3,
    "z": 2,
    "elements": [
        "minecraft:chest@0",
    ],
    "io": "output",
    "type": "item"
}

It would allow for much more natural-looking machines using existing blocks from other mods.
