Use product tree values when mapping engagements

Currently we can’t access the product mapper tree values while mapping steps in engagements. It would be very helpful to have a way to reuse the already defined product features/events, rather than needing to redefine the same things using CSS selectors in-app.

@shiraak thank you for sharing this here. We will look into the possibilities and get back to you.

@Namrata Mitra -Can you have a look at this.
