What are the limitations of transiting hours for a Velocity award booking?

Hi all,

Is it possible to book an award flight (Etihad) Gia Velocity points and transit in Abu Dhabi for 20 hours rather than the normal 2 hours that you get via the search results?

Is this allowed in Velocity award bookings?

Any advice or tips would be much appreciated.

It appears like you will have to select the next available flight to keep it as a single redemption.
