Use Ctrl + R to add all inputs to a Bundle, and connect them to the parent node of that tree. 

Use Shift + R to show Input Options, you can change (independently for all options) the name of the panel to be created, reorder the nodes, center the editor window to selected nodes, enable/disable inputs, rename them, separate vector inputs, and show a per input database names to fast renaming (the database is created while you actually change names, so at the beginning there will be no items).
