Xamarin Add another Section to Json

wondering if anybody can help with a solution I am looking for. In my Xamarin project, I have a 'add another line' button which adds another stack layout underneath it with the same controls as the first one. I want to save the new added one to JSON but not sure where to start, has anybody done this before?

I have added the first stack to json but i need it to reckonise the new ones on the button press. (sorry if it does not make sense)

Page.xaml Code:

`<Grid Margin="0, 30, 0, 30">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*"/>
                <ColumnDefinition Width="*"/>
                <ColumnDefinition Width="*"/>
                <ColumnDefinition Width="*"/>
                <ColumnDefinition Width="*"/>
            </Grid.ColumnDefinitions>
            <Grid.RowDefinitions>
                <RowDefinition Height="*"/>
            </Grid.RowDefinitions>
            <Label x:Name="NameLabel" Text="Name" TextColor="Black" FontSize="20" Grid.Column="0" Grid.Row="0" />
