Organize Accounts on the Same Target to Different Folders
This is a very simple thing to do. Create your folders. Add the target to both (or all) folders where you want them to be. Next go to the first one and add those accounts to the target that you would like to have in that specific subfolder. Do that with all the other folders.
Bare in mind that adding the same account twice (in different folder) might result on malfunctioning of (at least) one of the accounts. Because PassMan will consider these account (and targets as well) as being separate items when a change (of password) happens it will only change that on one account. So the other account will get out of sync.
