Dependent select without parent being saved to the database

I have a simple form based on a

WorkOrder

WorkOrder

. A

WorkOrder

WorkOrder

belongs to an

Equipment

Equipment

. An

Equipment

Equipment

belongs to a

Location

Location

. Therefore, a

WorkOrder

WorkOrder

belongs to a location through an

Equipment

Equipment

.

I have a dependent select working for the most part:

Forms\Components\Select::make('location_id')
    ->label('Location')
    ->options(...)
    ->live()
    ->dehydrated(false)
    ->afterStateUpdated(fn (Forms\Set $set): null => $set('equipment_id', null))

Forms\Components\Select::make('equipment_id')
    ->label('Equipment')
    ->options(fn (Forms\Get $get): array => Equipment::query()->...),

Forms\Components\Select::make('location_id')
    ->label('Location')
    ->options(...)
    ->live()
    ->dehydrated(false)
    ->afterStateUpdated(fn (Forms\Set $set): null => $set('equipment_id', null))

Forms\Components\Select::make('equipment_id')
    ->label('Equipment')
    ->options(fn (Forms\Get $get): array => Equipment::query()->...),

My problem is on form hydration though when editing the

WorkOrder

WorkOrder

. Since there is no

location_id

location_id

on the

WorkOrder

WorkOrder

table, it obviously doesn't fill the location. I need to somehow fill the location based on the selected equipment instead and that's where I'm stuck. Any ideas?
