Update selected data in select_group_ui

[yensmora]

I have a Shiny app that uses select_group_ui and select_group_server. I would like to have two buttons: one for the user to save a default selection and another to load it whenever they want. What I want is that when the 'load' button is pressed, the filters display the options saved (I suppose with the selected property). How could I do this?

Thank you very much.
