Send only the local paragraph to Grammarly to speed things up

[tmalsburg]

If I understand correctly, the complete buffer is sent to Grammarly which can be slow when the document is long. If there was a way to only check the local paragraph while typing that would be great. In addition, there should perhaps also be a way to request checking of the whole document. I have to say that I'm not familiar with flymake at all, so I don't know how to best implement any of that.
