Add event start date/location fields to custom post RSS feed

I am building a website using the Wordpress MyListing theme. I have created a Listing Type called "events", that, among many other fields includes the event 'start date' and 'event location'. I can access an RSS feed for events or at the category level, i.e. /feed/?taxonomy=region&tag_ID=102&post_type=job_listing This RSS feed has the post date for when the events were created/published, but it doesn't have the actual event start date (or event location). I need someone to write a snippet that will include the event 'start date' and 'event location' in the RSS feed, and have the feed ordered by event date. SIMILAR IMPLEMENTATION I have previously used The Events Calendar plugin for events on another website, and the same RSS issue was solved with the following solution: [login to view URL] It may be a case of simply modifying the snippets provided in the above solution. SUMMARY Develop snippet/s to modify the rss feed in the MyListing theme, specifically: 1) Add event date to rss feed 2) Add event location to rss feed 3) Order rss feed by event date
