Relcopy extension unique IDs

Having an issue with the ‘JQrelcopy’ extension. When inputs are cloned, they do not get a unique ID, so I have to do something like this in my view:


Thats good, except that when I have multiple fields from the same $model I want to put an index on them.









I see no way to do this. Has anyone altered the js code to autoincrement the IDs that are generated when records are cloned?
