I am trying to make a table like this one 
But having problems with the vertical text. Can anyone please help me to create the table? Thank you in advance.
My attempt
\usepackage{makecell}
\usepackage{supertabular}
\usepackage{array}
\usepackage{multirow}
\usepackage{rotating}
\begin{supertabular}{| c | c | p{4cm} | p{4cm} | p{4cm} |}
\hline
\multicolumn{2}{|c|}{\textbf{Title}} & \textbf{Title} &
\textbf{Title} & \textbf{Title}\\
\hline
\multirow{4}{*}[-3cm]{ \rotatebox[origin=c]{90}{R1}}
& A Lot of Text & really a lot of text really a lot of text
really a lot of text really a lot of text really a lot of text
really a lot of text really a lot of text & & \\
\cline{2-5}
& A Lot of Text & really a lot of text really a lot of text
really a lot of text really a lot of text really a lot of text
really a lot of text really a lot of text & & \\
\hline
\multirow{4}{*}[-1 cm]{ \rotatebox[origin=c]{90}{R1}}
& A Lot of Text & really a lot of text really a lot of text
really a lot of text really a lot of text really a lot of text
really a lot of text really a lot of text & & \\
\hline
\end{supertabular}
Update: I am able to create the table (not exactly but it will work for me). Right now my concern is to make it compatible with the multipage table.
