You have to program in LCN (Logical Channel Number) scheme. If you know the LCN numbers of the frequencies, you program them into the appropriate channel number in the bank. If you have an LCN of 1,2,3,4, you will program LCN 1 into channel 01 of a bank, LCN 2 in 02, and so on. Once the first channel is programmed with ED mode, the bank will be set ans the rest of the frequencies you program in the bank will remain ED and you won't have to change the mode until you put in frequencies other than EDACS.
