Wordpress plugin to create clashfinder

I require a custom plugin for my website that creates the effect of a Clashfinder. For an example of a clashfinder, see [login to view URL] This takes all acts playing at a Festival called Electric Picnic and the acts are mapped with their start and finish time along a timeline per stage. This allows people to see clashes of their favourite bands. I need a plugin that will allow me insert a clashfinder into our festival listing pages perhaps via a simple shortcode. Similar tools where people can highlight in different colours bands in their order of priority and highlight the bands they want to see would be extremely useful. It needs to have a simple and easy method of adding what might be 100 or more bands, times and stages to it's listing. So the breakdown would be a new clashfinder is created for each festival. So the clashfinder title might be Electric Picnic 2013. Then each stage should be added as an option. Then inside each stage a list of Day, Band, Time with multiple options so we can submit many at one time would be great. If no end time is known, it should assume the end time is the start time of the next act. If there is no next act, it should assume 1 hour performance.
