Adding additional attributes at pa.Field() level

Question about pandera

I need to add some kind of tagging to each field to tie it with use case. For e.g.

class ProductSchema(SchemaModel):
    name: Series[str] = pa.Field(kwargs={'usecaseA': true})
    price: Series[float] = pa.Field(gt=21, kwargs={'usecaseA': true})
    category: Series[str] = pa.Field(isin=['cat1', 'cat2'])

and then generate a list of fields required for a given use case. For e.g.
generate_mapping(usecase: "usecaseA")

which should give a dictionary obj as

{
 'usecaseA': {
  'ProductSchema':   ['name', 'price']
     }
}

Is it possible to tag the fields because **kwargs and dtypes_kwargs don't allow any additional parameters be passed they are registered check functions.

Hi @NeerajMalhotra-QB take a look at this issue: #1029

It should address your question. Currently no one's working on it but would welcome a PR contribution!
