Permiso familiar

I am trying to restrict the calls that a phone can take to only allow certain calls.  This plan only will allow 10 phone numbers to be allowed.  10 is a good start, but who does not know more than 10 people?  Is there a plan to increase that amount to say 30 or so?  10 does me no good, so therefore am not able to use it.

Dementia family member with 5 kids and spouses.  That is 10 right there.  Not to mention friends as well as Doctor's office. This seem utterly ridiculous.

Please rethink this option and allow more than 10 phone numbers.

Thanks for your time.
