I'm not sure what you mean by "label", but (almost all) elements that are displayed in the packet details pane protocol tree can be used in a filter, simply right click the element in the tree and use "Apply As Filter" | "Selected".
If you need multiple values of an element, then simply create additional filters, using an "or" (||).
When you have filtered to your satisfaction you can export the dissected packets using the menu item "File " | "Export Packet Dissections" | "As CSV...".
