Parameter control in DIVA for Grasshopper

I've been playing around with the demo version of DIVA 2.0 in Grasshopper, and I have been impressed by the improvements. However, I am struggling to understand one aspect of the implementation: All of the time controls for each of the simulations are accessed by a context menu. This makes it difficult to scrub through seasonal and hourly changes, or to search for critical points (perhaps by using Galapagos). Is there a way to control the simulation using param sliders—perhaps by using the sun position module?
