Format a one-field subreport to word wrap?

[Timberwolf]

I have a columnar report of training summaries that includes date, sponsor(s), attendees, trainers, and topics. The sponsor, attendee, trainer, and topic sections of the report are subreports. When there are multiples in each of these subreports (topics, for instance), it lists them like this:

General Credit
Disaster Assistance
Marketing Assistance

Is there a way to get it to list them like this (using word wrap):

General Credit; Disaster Assistance; Marketing Assistance

Thanks!
