Paginated Report Builder - Repeat Text Box when Tablix off the Page

Hi there,

I am trying to create a paginated report, but I am struggling with the following problem:

I have a TEXTBOX [with an expression to retrieve the question header from a survey] and a MATRIX [that shows the answers that were given on a selected question from the survey]. The rows from the MATRIX can be very long, and may required more than one page when printed as a PDF. I have set a parameter for the column of the MATRIX, in a way that I may selected several items and the matrix columns grows to a amount of columns that can not be shown in one page when printed as a PDF.

The issue I am facing is that I can't set up the TEXTBOX to repeat itself, when a MATRIX scrolls of the page in a PDF report.
Please see the images below:

a. Image 1 - Initial set up of the Paginated Report
1 - represents the TEXTBOX that retrieves the question.
2 - represents the matrix that show the results

b. Image 2 - shows the result of a 2 PDFs pages, when i run my paginated report.
I would like the TEXTBOX, highlighted in RED, to show in the second page [in the box highlighted in YELLOW], since the 'matrix' in the second page represents the continuation of the matrix from the first page

c. Image3 - a similar problem occurs when my MATRIX grows to the RIGHT of the page and doesn't fit in one page. The textbox does not REPEAT on the following page.

I have been reading posts on the internet trying to solve this problem, but I have not been successful.
One of the solutions suggested was to insert a rectangle in the hearder of the matrix but unfortunately this doesn't work for me, as the columns can grow based on a parameter that is selected. I would like the 'TEXTBOX' to have a fixed size on top of the Matrix, regardless of how many items are selected for the columns of the Matrix.

Can anyone help, please?

Thanks in advance
