Convert regular Go struct to Terraform struct and back

I am making a very simple datasource in the Terraform-plugin-framework.

Terraform wants me to use their custom types in structs in order to modify state, like this:

type HumanModel struct {
	Firstname types.String `tfsdk:"name"`
	Lastname  types.String `tfsdk:"owner"`
)

In my datasource, I make a request to my API, which returns a regular go struct like this:

type NetworkHumanModel struct {
	Firstname string `json:"name"`
	Lastname  string `json:"owner"`
}

Right now, I unmarshal the object I get back from my API to my NetworkHumanModel struct, then I convert that struct to the HumanModel struct. Currently I do that this way:

//data = HumanModel
//response = NetworkHumanModel
data.Firstname = types.StringValue(response.Firstname)
data.Lastname = types.StringValue(response.Lastname)

resp.Diagnostics.Append(resp.State.Set(ctx, &data)...)

Its a lot of manual labour to do this with bigger responses and POST requests, is there a quicker way to convert between the two structs?
