Preventing duplicate phone number fields on booking form

Hi Support Team,

I am reaching out because I would like to prevent my booking form from asking for the client's phone number twice.

I currently use a workflow that sends an SMS reminder 1 day before the meeting. However, this setup seems to trigger a second phone number requirement on the intake form. Since I cater to busy professionals, I want to streamline this experience and avoid any double-entry.

Is there a way to consolidate this so the phone number is collected only once and automatically applies to the reminder workflow?

Thank you in advance for your help,

Carine
