Logic Block builder Table Lookup variable instantiation as functionality?

When a variable of type Table Lookup is instantiated, it seems to me there should be an As field so you can define what table the table lookup points to.

Was this ever a thing? Should it be a thing? For instance here I want to create a Table Lookup to Directory, but places that expect a TL to directory to be passed/set won’t accept a Table Lookup instantiated like this which is missing the ‘As’ functionality.

From research I did, this was never a thing, but there’s an existing idea in the Nextworld backlog that requests it.
