Event properties missing – google throws warnings

When I test my pages with structured data for an “event” type with the google test tool it throws several warnings for missing optional fields:

• “eventStatus“
• “offers”
• “organizer”
• “eventAttendanceMode“

I would love to fill that fields, but the WP SEO Structured Data Schema plugin doesn’t offer these fields for the event type.

Especially the fields eventAttendanceMode (Online, Offline, Mixed) and eventStatus (Cancelled, MovedOnline, …) seem very useful and important nowadays.

When will WP SEO Structured Data Schema add support for these event fields?

(Technical information about the event schema as google currently understands it)
