The process is the same as for when you setup a program for yourself. However, instead of having your DNA sample in the remote, you put theirs in.
By the way, for each generator, it can only run one program at a time. You don't add frequency sets for others into the same generator you are running frequency sets for yourself unless you wish for everyone to get all of it. There's no method to have the generator selectively send one set to you and another set to someone else.
