shared IMAP account

Hi!

I have the following use case: I share an IMAP account with other persons. We 
are using this as a group email address. Is it possible, to have local 
read/new states for the mails in KMail, like local subscriptions work?

I men normally when you use one IMAP account from two locations, you want to 
have messages marked read on both locations, if you read it on any of those 
locations. 

I would like to have the opposite: each location should have their own read 
states. Is that possible?

Bye...Frank
