Same PCG script, different tags on splines

I have a PCG graph that covers an area with both open and close-loop splines that are accessed by tag.

It means that I want to use this graph in another location, with other tags, or no splines, I have to duplicate the graph and change the tags. There is another tag setting that looks like you could add multiple tags, but that is deprecated.

Is there a way to make it a parameter, and add more if needed?
