Linking Opportunites to Account List View

Hello,

We are listing our accounts via the default account list view.

I have added some extra columns to this view from the opportunity
summary (Close Date, Source of lead etc).

The problem is that any data from the opportunity is either coming up
as blank or "none".

I know the linking is there because I can access the opportunity record
via the individual account record.

Could someone please advise if it is possible to list the opportunity
information in the account listing?

Thanks,
Mark
