Did you find a solution for having multiple records of same type for the same name? E.g. for and a domain apex when using GitHub pages:

var aRecords = [
  {
    name: '@'
    ipv4Address: '185.199.111.153'
  }
  {
    name: '@'
    ipv4Address: '185.199.110.153'
  }
  {
    name: '@'
    ipv4Address: '185.199.109.153'
  }
  {
    name: '@'
    ipv4Address: '185.199.108.153'
  }
]
