This can very easily be done using microsoft excel.  You can draw borders 
around your individual or group residues, make residues bold or larger than
the others, and if you happen to have a color output device, you can print
different colors for classes of residues.  

I have done this extensively on my mac, and an example of such an alignment,
complete with color, can be found in the following reference:

Wiederrecht,G. Brizuela, L., Elliston, K., Sigal, N. and Siekierka, J. 
"FKB1 encodes a nonessential FK 506-binding protein in Sacharomyces
cerevisiae and contains regions suggesting homology to the cyclophilins."
Proc. Natl. Acad. Sci. USA  88:1029-1033. 1991.

(I couldn't help joining in the latest bionet craze of citing ones own work!!)

Anyway, you can automatically load the output from several multiple sequence
alignment programs (like clustal) by placing a tab between every character
in the alignment, and then pasting this into excel.  I wrote myself a simple
hypercard script to do this, but you can do it any way you like.  Then, just
edit the alignment to your hearts content, with one residue per cell.

Good luck.
