This is fairly common - a Sharpie works well.
Keep in mind, a large stadium act (which appears in the picture) changes drum heads every couple of shows. If you leave the same head on for a year, this may not be a good idea. If you still have the same set list after a year.......well maybe you need new songs.
Also - keep in mind, the average club band needs about 40 songs for a 3 set gig - that's too many to write on a snare.
