Default value for @exported custom resources

Question

Is there a good way to set a default value for exported custom resources? So far I have tried:

@export var health: Stat = Stat.new()

But this A. does not set it to a default value, not even a blank resource and B. does not let me set a value to any of the resource’s properties

I also tried this:

@tool
extends whatever

@export var health: Stat = newStat(100.0)

func newStat(value: float) -> Stat:
	var newStat: Stat = Stat.new()
	newStat.base = value #base is a variable in Stat
	return newStat

This works, but it requires my script to be a tool script, which I would like to avoid if possible, is there a better way to do this?

Save the default to disk and then:

@export var health: Stat = preload("res://default_stat.tres")
