Does 1PW no longer maintain previous passwords?

I am not sure this is part of, or related to, this discussion, but what I expected to see and want to see is any field set as password should have the feature that you can see it's 'history', that is, the past passwords the field used. Think of the scenario where you have one client you work for and you set the 1password entry up as a password but it in reality is is a series of IDs, urls and PWs: say one to get onto the vpn and others for email, Remote Servers, and applications. Only the first password will have the 'history' function. Or am I wrong in some way. Should the entry be created as something other than a login or password? My work flow would be impacted to have separate entries for each ID/PW associated with a single client. If you know a way to achieve my goal please let me know. Thanks.
