Initial SOA records conflicting with `INCEPTION-INCREMENT`

[c33s]

to create a SOA record for a domain i have to use powerdns_record like this:

resource "powerdns_record" "SOA_example_com" {
  zone    = "example.com."
  name    = "example.com."
  type    = "SOA"
  ttl     = 3600
  records = ["dns1.example2.com. hostmaster.example.com. 2019120101 10800 3600 3600000 3600"]
}

which creates a record with this entry. if i have set my soa_edit_api to empty according #29 it works like charm but of course it is much better to have set the serial automatically. so if i set soa_api_edit to INCEPTION-INCREMENT i get a conflict because the serial got increased automatically and isn't equal to the serial set in the terraform config before:

• running terraform apply creates the soa record (with the config above)
• the serial gets increased automatically
• running terraform apply again results in this:

      id:                 "example.com.:::SOA" => <computed> (forces new resource)
      name:               "example.com." => "example.com."
      records.#:          "1" => "1"
      records.xxxxxxxxx9: "ns1.example2.com. hostmaster.example.com. 2019120102 10800 3600 3600000 3000" => "" (forces new re
      records.xxxxxxxxx2: "" => "ns1.example2.com. hostmaster.example.com. 2019120101 10800 3600 3600000 3000" (forces new re
      ttl:                "3600" => "3600"
      type:               "SOA" => "SOA"
      zone:               "example.com." => "example.com."

so how to use this provider to create an initial SOA record but increase the serial without this conflict?
