### Summary

I have 20K lines of schema for real app. I don't need/want to modify all this stuff. 
I would like to limit inference/autogeneration for 3 tables for example. Is it possible? 

I think would like such UX:
```
$ Which tables you want to expose?
> TableA
> TableB
[enter]
$ Which operations for TableA?
> Update
>Which for TableB?
> Delete, Create
```

I hope this helps to explain what I want.

I don't mind inference for everything but I would like to limit what's available in graphql.
