Question ReportContainer and Linked object

Hello. I’m using LL21 with Win10PRO .
I have the following situation: ReportContainer with two master and detail tables . In the bottom of the page I have a layer that appears only on the last page and are connected to ReportContainer.

The first problem is that I can not make the top “master” are printed in the same lines of the page “detail” when there is a page break.

The second problem is that I want to avoid having the situation where ReportContainer end up on a page and the layer, which I make visible the last page, to finish on a new sheet.
