[Ifeffit] Debye-Waller factors for metal oxides ?

Dr.Rehr mentioned the calculation of DWs using spring constants with the equation-of-motion method(EM) and the recursion method(RM). I wonder if these two methods can be incorporated into ifeffit like Debye and Enstein model. I use EM to calculate the DWs for metal complex molecules, and they work pretty well for a preliminary analysis, but I have to input the calculated DW factors into Artemis one by one manually :-( Ye
