2 groupwise accounts in 1 Groupwise client

2 questions.

1) Is it possible to have 2 Groupwise accounts in one Groupwise client without adding the 2nd account as either POP3 or IMAP? the situation is when the user has two email addresses within the same GroupWise domain.

2) If number 1 is possible, can it be possible as well if the user has email addresses from 2 different Groupwise domains?

Many thanks!
