Phone number country code in list details block with item detail button

Hi! I am using an item detail button so that users can update their phone number (along with other contact info) in their user profile (displayed with a list details block). Data is populating from airtable, which has the phone number field displaying the area code and phone number - all are US numbers but because they come from a customer completed form, none currently contain the +1 for the US prefix.

Is there any way to tell softr to default to/always use the USA prefix? or is the only option to modify the data in airtable so that it adds the +1 ahead of the phone number for the country code to display correctly in Softr?
