It's kinda like opposite of "remove and rewire".
In some cases we need to insert two end function node to wire repeatly, for example I might need to insert a lot feedback node when debugging FPGA code.
Right now we need to select a wire, select function (4+ clicks or so?), let alone we have to move the mouse cursor.
It would nice if we can set a shortcut for these kind of operation, say, we might select a wire(or maybe more then one wire?), then we press like Ctrl+1, we will automatically insert function 1 in this wire(s), which user could config themself.
