Improve user experience when a meeting is booked from the main page of the Release Planner app

Right now the user is sent to the main page of the Scheduler tool so when they select the meeting they want, we don't have the information of what Release plan the meeting is going to be for.
We should look into how can we improve this

Start by tracing the booking flow from the Release Planner app's main page into the Scheduler tool. Determine how the selected meeting can retain or display its associated release plan, then define completion as the user being able to identify the release plan when selecting the meeting.
