Hi Aaron,

thank you for reaching out to us!

Unfortunately, at the moment, frontend booking requires set date and time to be chosen by a client.

Alternatively, you can hide Amelia from the site and make backend bookings only.

You can suggest that as a feature request here, or check if there is such request there and vote for it. 

If you have any other questions or concerns feel free to open a new ticket and we will gladly help out.
