I encounter this often. Here's a small workaround I use.
I copy/paste the struct into a new VSCode tab and do the following
find/replace
Search: `.+#.+\n`
Replace: `` (aka nothing)
Then you can format. E.g. this turns:
```
%User{
__meta__: #Ecto.Schema.Metadata<:loaded, "users">,
id: 123,
primary_contact_id: 456,
primary_contact: #Ecto.Association.NotLoaded<association :primary_contact
is not loaded>,
name: "Name",
created_at: ~U[2023-03-27 20:27:27.756360Z]
}
```
into
```
%User{
id: 123,
primary_contact_id: 456,
name: "Name",
created_at: ~U[2023-03-27 20:27:27.756360Z]
}
```
This doesn't really address your concern, but I do it so frequently that I
figured I'd share.
