Suggestion for fly out menus

Hello. I am trying to replace my taskbar with object dock and there is only one thing missing. On my taskbar I have several folders and libraries pinned to the file explorer icon for quick access. I have tried to recreate this with stacks and the fly out menu but it doesn't work quite right, they are both slower than the jump list and require more mouse movement to make a selection. Does anyone have any ideas or could this be added as an option to the flyout menu for just a vertical list of folders like a jump list.

Thanks for your help.
