"If-need-be" allows you to indicate that you can make a selected date 'if-need-be' (i.e. it's not the best date but you could make it if you have to).
- Click on one of the options to vote yes.
- Click on the same option again to vote 'if-need-be'. You will see that the option turned yellow to indicate your "if-need-be" vote.
- Finish by clicking "continue".
