Phone Number Placement in Onboarding

Currently, the phone number field is listed on a members Profile (under Account Settings) but this field isn't present in any of the default onboarding procedures. Meaning that for our members to fill out their phone number, they'll need to fill it out after the fact or I need to add another Attribute that is called phone number. If I add an Attribute, there are then two listings for phone number on the Profile page (confusing for members). This seems like a fairly simple request but simply removing the phone number from the top of the Profile section or adding it as a default part of the onboarding would fix this.
