Get html.Div() input from another layout

Hi,

I have a main layout, that returns another layout, named layout ABC for example, upon user’s calls:

@app.callback(
    Output('table1', 'children'),
    [Input('user-request', 'options')]
)
def update_status_table(user_request):
    return ABC.layout

As I see, layout ABC is able to call Dash components from the main layout, but not the other way.

There is a hidden html.Div() inside layout ABC that stores the data for components in layout ABC.

My question is, is it possible to call that hidden html.Div() from an other layout XYZ, which is also linked with the main layout ?

Thank you.
