Is it possible to override the material of a GPUParticles3D?

Question

Meshinstances have a surface override property which allows you to swap in a different material at runtime. Is it possible to do the same for particles or is a separate resource or node required?
Currently I’m using a solid albedo colour that changes depending on a couple of other variables to set the colour of MeshInstances:

var clr:Array=(colour_defaults[num] if colour_use_defaults else colour)
for thing in visibles:
	var targ_clr
	thing.set_surface_override_material(0,thing.mesh.material.duplicate())
	targ_clr = thing.get_surface_override_material(0).albedo_color
	for rgb in 3: targ_clr[rgb]=clr[rgb]
	thing.get_surface_override_material(0).albedo_color = targ_clr

The closest I’ve gotten with GPUParticles is this, which changes it for every instance in the scene:

var clr:Array=(colour_defaults[num] if colour_use_defaults else colour)
for thing in visibles:
	var targ_clr
	if thing is MeshInstance3D:
		thing.set_surface_override_material(0,thing.mesh.material.duplicate())
		targ_clr = thing.get_surface_override_material(0).albedo_color
	elif thing is GPUParticles3D:
		targ_clr = thing.draw_pass_1.material.albedo_color
	else: break
	for rgb in 3: targ_clr[rgb]=clr[rgb]
	if thing is MeshInstance3D: thing.get_surface_override_material(0).albedo_color = targ_clr
	elif thing is GPUParticles3D: thing.draw_pass_1.material.albedo_color = targ_clr

Fixed by just making two separate identical particle effect scenes. Not ideal but works
