I have researched this topic but didn't find a satisfactory answer.

I have created a DW template with repeating regions. In DW I am able to get
the region to repeat....

Edit > Repeating Entries > Copy Repeated Entry

then

Edit > Repeating Entries > Paste Repeated Entry.

But I am unable to figure out how to tell my client how to do this in
Contribute 4. Can someone help me with this?
