[Feature Request] Expand the API to add specific nodes instead of all nodes with that name

[DustyBagel]

I think it would be a good idea to expand the API so that you can add hopper support for a specific node like at a given position instead of all nodes with a specific node name. For example, say I want to add one default:chest node instead of all default:chest nodes so that a hopper works with that one chest node and not all of them. This would be useful if you wanted to add support for a specific node under certain conditions.
