How can I use ""Copy Master & Detail Record"" function in Quickbase to only copy a specific subset of child records from a master template?

I use IOL and jquery for the API calls. My app definitely has a lot but they're really just copy paste after the first couple conditions. Happy to show you and send a few examples you could tweak and use for yourself. I know you only have a few things later but if later on you need it to scale you'll have everything you need already.
