[Ifeffit] Two edge problem (in the same scan)

Hello everybody, I have a question/problem. Last year during the EXAFS course at NSLS, I had requested Bruce if it is possible to analyze the data with two edges. For example, I have the data for As and Se K-edges, which I collect in the same scan. In WinXAS program, I can section the edges and analyze them separately. At that time, the program was not able to perform these edges or the sectioning. Have we reached this possibility. I tried again using the latest updated Athena, but it seems not to be working. Can you please tell me whether the sectioning or dealing with two edges in the same spectra can be done Ashtosh
