Desktop APP Personal Contacts: Custom Label for Phone Number

We have users that would like to see the ability to create Custom Labels for the Phone Number for the contact. Creating a custom label instead of using "Other" (or the other predefined labels) would allow them to know exactly what type of number they are calling. EX: We use a vendor for call recording (recording insurance claimants statements) and the ability to add a custom label such as "Call Recording IVR" could be beneficial", especially if a business has several different contact numbers.
