Using subtypes and domains for a tree layer

Question

I have a point layer in ArcGIS Pro with trees, set up a table with 2 fields Family and Tree species, including domain lists. So dFamily = "Quercus" (oak) and "Salix" (willow) and dSpecies = Quercus robur, Quercus petrea, etc. Some families like willow have a lot of species, so that list is long. When i add a new point/tree on the map and select field Family = Quercus, I would like in the field Species ONLY the Quercus species and not the whole list of all the tree species. How to do that? Using domains and subtypes, but how?
