Adding query parameters `merge-from` and `merge-to` for PRs?

[superarts]

Is it possible to add query parameters merge-from and merge-to for PRs, so that we can filter PRs that's from/to certain branches with keyword/pattern please?

It would be handy if we can search PRs from bugfix\/.*, or PRs to develop. Currently we have to manually add keywords in title, or use labels to achieve this.

Is this for GitHub or one of the other supported services? Do you know if the given API client supports these types of queries?

this would be a huge improvement. very much needed to know what branches the merge happened.
