Nested pages subroutes with go_router (Flutter)

My app structure can be like this:

home/folder/:fid/player
home/folder/:fid/folder/:fid/player
home/folder/:fid/folder/:fid/folder/:fid/player

with nested folders that can open other folders (a folder can contain an audio file which plays in the player) etc

Is this possible with go router? I've tried to do something like this instead:

home/folder/:fid/folder2/:f2id/player

but it is getting very messy. My router currently looks like this

 final router = GoRouter(
      routes: [
        GoRoute(
            path: HomePath,
            builder: (context, state) => HomeWrapperWidget(),
            routes: [
              GoRoute(
                path: 'session/:sid',
                routes: [
                  GoRoute(
                    path: 'player',
                    pageBuilder: (context, state) =>
                        getPlayerMaterialPage(state),
                  )
                ],
                pageBuilder: (context, state) =>
                    getSessionOptionsMaterialPage(state),
              ),
              GoRoute(
                path: 'folder/:fid',
                routes: [
                  GoRoute(
                    path: 'folder2/:f2id',
                    routes: [
                      GoRoute(
                        path: 'folder3/:f3id',
                        pageBuilder: (context, state) => getFolderMaterialPage(state),
                      ),
                    ],
                    pageBuilder: (context, state) =>
                        getFolderMaterialPage(state),
                  ),
                ],
                pageBuilder: (context, state) => getFolderMaterialPage(state),
              ),
              ...
            ]),
      ],
    );
