Hard to use parameter for "venue book" command

[Isaaclhy00]

The "venue book" command uses the index of the resident in the Resident list in order to specify which resident is booking the venue. However, if the user is in the Bookings view, the user would have to swap back to the Residents view just to check the index number of the specific resident. Perhaps using the name as the parameter instead of the index would be a better idea.
