Open Rail Designer - multiple element regression analysis?

Hi,

I'm looking for a tool in Open Rail Designer similar to "multiple element regression analysis" (tool in Power Rail Track). I want to connect two lines in a more complicated way than "spiral - arc - spiral" (for example "spiral - arc - spiral - arc - spiral" or "spiral - arc - arc - spiral". Is there any tool in Open Rail Designer that can do something like this?

Thanks

DR
