Is it possible to exclude country code when passing phone number as a URL parament?

Using typeform with ScheduleOnce. I am able to successfully pass name, email and phone to our schedule once booking page so those fields are auto filled.

HOWEVER… since ScheduleOnce has a seperate field for “Country Code”… it errors out when phone number includes the country code.

For example:

555-555-5555 works great

+1 555-555-5555 causes an error in ScheduleOnce and the user must manually remove the country code.

Is excluding the country code when passing the phone parameter possible? Or better, is it possible to pass the country code and phone number as two separate parameters

EXAMPLE:  site.com?country_code=%2B1&phone-555%20555%205555
