fix footer on first page of form

I have a form with two master pages, the first has a header, content and footer and the second has a header and content part (the header is different from the first page). This footer must only appear on the first page, without repeating on the others and be able to break the page in case of very long text (or have a dynamic size, where it is possible to increase and decrease according to the size of the text). The problem I'm having is that leaving the footer on the master page does not allow line wrapping and when I leave the "expand to fit" option checked, it ends up "cutting" the field, as it expands downwards and there is no more space. I would like to know how, if any, I could be resolving this problem?

A estrutura atual é:

- Páginas-mestras
- Subform cabeçalho
- Área de conteúdo
- Subform rodapé

No subform do rodapé:
- Texto (título do 'bloco')
- Tabela com 1 linha
- Linha1
- Tabela com 1 linha
- Linha1
- Duas tabelas:
- Tabela 1: Linha de cabeçalho e linha de corpo,
- Linha de cabeçalho: título do campo
- Linha de corpo: campo do texto do rodapé
- Tabela 2: Linha de cabeçalho e linha de corpo,
- Linha de cabeçalho: título do campo
- Linha de corpo: campo do texto do rodapé

I'm from Brazil, so the writing is in Portuguese.

Thanks,
