I have an older plugin installed that is firing all these PHP Deprecated and PHP Notices in my debug.log every time a page loads. Is it possible to mute PHP Deprecated and PHP Notices but ONLY for files in my plugins directory? I value a clean debug.log as it helps with making sure my code is error-free during development, but this kind of stuff makes it all messy.

More Details: I don't want to turn off all PHP notices because I like to have those to make sure my own code isn't creating any notices.

This plugin is something my client wants that is not worth the time to fix/replace/build from scratch, so I'd prefer to keep it.
