There is additional learning overhead involved, and at present the sp.correlogram() function for Moran's I just reports the values of the estimated statistics for each lag, but can be easily changed to plot +/- 1 or 2 * sqrt(var(I)). Going from there to "significance" would depend on adjusting the p-values because multiple tests are being made on the same (overlapping) data. If you would describe your research problem a little more, I can see whether the functionality you need can be added to the function.
