Conventional Commit based on pull request `title`

**Is your feature request related to a problem? Please describe.**

Hi guys,

Adding labels is really nice, however prefixing the title of the PR can be some much more fun. See for example how it looks here https://github.com/felangel/bloc/pulls?q=is%3Amerged

**Describe the solution you'd like**

Auto has https://intuit.github.io/auto/docs/generated/conventional-commits plugin, however it seems that the plugin uses the individual commit messages.

It is possible to have the plugin use the title of the pull reqeust for the conventional commit logic instead?
