[chirp_users] Memory bank programming?

I'd like to IMPORT memory bank programming from Excel but don't see a way of getting the correct Columns or Sheet to start. I've tried doing a download from the radio (FT-7900 and FT-60) and then doing an EXPORT. I don't see the memory banks in the exported .csv file. Is memory bank programming something CHIRP supports? Thanks -John K7TY
