In Great Expectations, GX Core 1.0+, for its Python API, you know if it is possible for a checkpoint to have varied batch parameters per each `gx.ValidationDefinition` instance passed to it?

Say, I want every validation definition to be bound to a particular dataframe. But if I pass batch parameters to a `gx.Checkpoint(...).run(batch_parameters={"dataframe": df_xyz})` method, it just passes that dataframe to all validation definitions.

How do I work around this? I know you can get a checkpoint per each individual validation definition, but this is something that I would like to avoid as much as possible.

As per Tyler Hoffman in GX Slack:

> Hey @Владимир Вилимайтис we discussed that, but for now landed on one
