Total traffic of multiple servers

[Frenzel]

I created a total traffic (outbound) graph of the traffic of multiple servers.
After lots of headaches and much of forum reading I have it almost working.

My template is based on this howto: http://forums.cacti.net/about5703.html

View problems left:
1 - I create a template for 10 servers but not always I want to add 10 servers to the template. So I need a dummy source with a default value of 0. How do I create this?
2 - Also I like to have a 95 percentile line on the total of the traffic. I have a 95 percentile line but it seems to base it on the first traffic line and not the total.
3 - Now I have all separate servers traffic also in lines/areas in the graph but actually this is not usefull, is there a way to shown totals but without the separate traffic lines?
