This feature is missing in your library and i think it would be awesome to have it. I can also contribute if you want.

If the community wants this feature, the community should make a PR for it. My time is not unlimited, and I have a lot of projects to maintain. In the following days, I'll make a few commits, release an important announcement about this library and its future and release another version of the library.
