Latex - change section indexes

While using latex for a university project I came across the problem that the indexing of the latex sections did not match the section indexing from the task specification. The default section indexing in my latex editor goes as follows: \section returns 1, \subsection returns 1.1, \subsubsection returns 1.1.1. However, I needed the \subsubsection to result in an alphabetical indexing. So, the solution that I found was changing the subsubsection definition using the following statement: \renewcommand\thesubsubsection{\alph{subsubsection})} It is important to notice that latex would use this indexing for the rest of the document if not specified otherwise.
