Reports & Discoverer :: Oracle Report Dynamic Text Movement

I have one report requirement like below diagrams, My report having one repeating frame and one dynamic LOGO field. My repeating frame have 2 field say item_no, and item_name. This repeating frame will grow based on the items say min 1 to max 8 items.

My dynamic logo has some min and max movement position, Say in the below diagram my dynamic logo min movement position is line no 6 and max movement position is 9.

Suppose i have only 1 or 2 or 3 or 4 or 5 items then LOGO should fit in the line no 6, if i have 6 items then logo should come in the 7th line, if i have 7 items then logo should come in the 8th line ect.,like that max 8 item will come in the report, if items are 8 then logo should fit in the 9th line number.
