Groupwise client’s group membership

Groupwise Experts I need your help.
Okay I will admit this, I am a old Exchange person and I can argue the pros and cons of MS-Exchange vs GroupWise all day long. Both systems have their merits and I can play devils advocate for either system. One function I do miss, how can I easily find out what e-mail groups a individual is a member of without looking at every group one by one? With exchange client (outlook), you can right click on the user’s name in the address book and see what groupshe/she is a member of. This helps administration of very large e-mails systems easier with Exchange then GroupWise. Any ideas on how I can determine group membership using the GroupWise Client or any other utility?
