Can optimal power be calculated by using the GSA IDW in Model Builder?

I have to derive 36 IDW interpolations for 36 years.  I was using the Geostatistical Analyst Wizard to calculate for each year the optimal power (that reduces the RMSE).  However, I was having to do this for each layer as there was no option under the IDW in the Geostatistical Analyst Toolbox to do this (always defaults to 2). 

Is there any way that I can  run IDW on all 36 years in model builder - such that is is calculating the optimal power?

Any suggestions welcomed!
