gml - How to get access to the instance variable within the Create event?

Question

I have this code in GML2 Create event

inst1 = instance_create_layer(100, 100, "Instances", obj_genus)
inst2 = instance_create_layer(200, 100, "Instances", obj_genus)
with inst1 {
    txt = "Ying"
    related = inst2
}
with inst2 {
    txt = "Yang"
    related = inst1
}

But I can't use inst1 or inst2 at this time. I get the follower error:

ERROR in
action number 1
of Create Event
for object obj_game:

Variable obj_genus.inst2(100006, -2147483648) not set before
reading it.
at gml_Object_obj_game_Create_0(line 5)-     related = inst2
##################
gml_Object_obj_game_Create_0 (line 5)

I create pairs of objects which are related to each other. Is it possible to wait in the Create event, until the object has been created? Unfortunately there is no Post Create event or something like that.
