Different Title in Header for each Subreport / Additional Header in Subreport

I would like to have a Header that contains a different title for every detail band in the masterReport.

Scenario:

I do have the following layout:

MasterReport

• PageHeader -> containing HeaderSubreport & a textFields for "Page / Pages"
• Detail1 -> containing DetailSubreport1
• Detail2 -> containing DetailSubreport2

HeaderSubreport

• containing Logo & TextField for a HeaderTitle

DetailSubreport1

• containing Data1 -> should have Title1 in Header

DetailSubreport2

• containing Data2 -> should have Title2 in Header

Question

Is it possible to define a PageHeader Band in the Master & a Subreport ? (I tried it but it lead to infinite loop)

Most desired I would like to keep the HeaderSubreport in the PageHeader band of the MasterReport (because of single place of declaration and because of textFields "Page / Pages". But I have to set the title depending on the current DetailSubreport that is currently processed.

Is there a possibility to set a global variable in the detail band of the Masterreport?
