Borders in ODS

Hi, all!
I need little help, or just configmation that what I want is impossible. I have ODS report with two nested loops, and it works ok, but I need one more feature. For better visibility I need border line between elements of outer loop. If I set border between ends of loops, it is ignored. I can only add empty line, and then set border, bit it is not what I need...
Thanks...
