Signature on the last page of a report, but not on an extra page

Hello,

I have a very complicated Report with many frames. I'm working with Report Builder 12.2.13.0

Depending on data some frames are suppressed, some not. So it cannot be said which of the frames is the last that is displayed.

Now it is necessary to print a Picture (Signature) ONLY ON THE LAST PAGE of the Report.

I've tried 2 possibilities and both were not successful:

1. put the field with the signature into margin-section where several other fields are displayed --> I cannot find out how to print one field only on the last page.

2. put the field at the end of main section --> It is not allowed that signature is alone on a page --> How can be achieved that there is no page-break before the signature?
