Fetching partial README.md file from GraphQL API

Hi everyone,

I’m using Github’s GraphQL API to fetch a number of public repositories with their respective README files by using the object(expression): blob field of the Repository type. That works great but several of those README files are massive so, in order to reduce the amount of data sent over the network, I was wondering if there exists any mechanism in Githubs API to fetch fragments of blobs, like the first 500Kb, or the first 100 lines or any other kind of truncation. Thanks!

Regards
