We assume you've already prepared pages for each staff member. To create their very own booking forms, when adding the booking form to their page, hide the Employee field, but be sure to choose the default value for that field.
In the modern booking forms, click on a staff card when you edit the appearance of your Staff form. Then, select 'Custom' on the right and choose the staff member that you want to display to your customers. Copy the unique shortcode provided for this form and paste it into the page editor where you want the booking form to appear.
Staff tab can be hidden if necessary.
