Niagara Ribbon Renderer - close the loop?

Fairly simple question - I have a sequence of particles with a normalized RibbonLinkOrder attribute - the ribbon begins at 0.0 and ends at 1.0. How do I close that gap? I can only think to spawn another particle in the same location as 0.0 and recalculate the RibbonLinkOrder to accommodate the extra particle, but I would like to know if there is a better way?
