Use Append rather than AppendTo

M = {{0, 1, 2}, {4, 5, 6, 7}};
M = Append[#, 8] & /@ M

{{0,1,2,8},{4,5,6,7,8}}

Hello--

I would like mix use of Map and AppendTo in the following way (e.g.):

M = {{0,1,2},{4,5,6,7}};
AppendTo[#,8]&/@M;

Of course, this doesn't work, because {0,1,2} is not a symbol name,etc.
Is there a way to use Hold or Sow to make this construct work?

Thanks!
