How to edit/change listing from frequent availability to infrequent

[James7]

When I set up my latest listing Airbnb asked if the listing would be frequent or infrequent (or similar terms) I chose 'frequent' and I see that this makes my listing available out months into the future.  I wish to now edit my listing such that I control/turn-on the future availability - might anyone know if this is possible or must I delete the listing and start over?  Gracias!
