FIM object person with a collection of another Object (Entity)

Hi,

I have in FIM a Person object with several attributes I would like to group.

The person object has a lot of attributes like: entity1phone,entity1mail, entity2phone, entity2mail, ...entity10phone, entity10mail.

I would like to have an Person object with a collection of Entity objects where the entity object should have the attributes phone and mail.

Can I do this? How?

Many, many thanks,

DD
