Is there a way to hide all or several images at the same time?

I am writing code to hide/show certain images of a map based on user selection. Is there a more efficient way to do this? My current solution is writing several separate app.mapname.visible = 'off' lines for each image. There will be likely 100s of images used.

% Value changed function: ChooseBayDropDown
        function ChooseBayDropDownValueChanged(app, event)
             value = app.ChooseBayDropDown.Value;
             
             switch value
                 case 'Bay 1 - Receiving'
                  app.bay1_map.Visible = 'on';
                  app.blank_map.Visible = 'off';
                  app.bay2_map.Visible = 'off';
                  app.bay3_map.Visible = 'off';
                  app.bay4_map.Visible = 'off';
                 case 'Bay 2 - Heat Room'
                  app.bay2_map.Visible = 'on';
                  app.blank_map.Visible = 'off';
                  app.bay1_map.Visible = 'off';
                  app.bay3_map.Visible = 'off';
                  app.bay4_map.Visible = 'off';
                 case 'Bay 3 - A-Plant'
                  app.bay3_map.Visible = 'on';
                  app.blank_map.Visible = 'off';
                  app.bay2_map.Visible = 'off';
                  app.bay3_map.Visible = 'off';
                  app.bay4_map.Visible = 'off';
                 case 'Bay 4 - Hot Cast'
                  app.bay4_map.Visible = 'on';
                  app.blank_map.Visible = 'off';
                  app.bay1_map.Visible = 'off';
                  app.bay2_map.Visible = 'off';
                  app.bay3_map.Visible = 'off';
             end

Thanks!

You can use findall to get a handle of all the uiimages.

    handle = findall(app.UIFigure,'Type','uiimage');
                for ii = 1:length(handle)
                    handle(ii).Visible = "off";
                end
