Yeah, you can use the dsidescription, but you are not defining it. You can try:
On ##HOST## for database ##auto.dbname##, SPID ##auto.blocked_spid## (run by ##auto.loginname##) is being blocked by ##auto.blocked_by_spid##. The last batch was ##auto.lastbatch##. The command is ##auto.cmd## and the program is ##auto.program##.
Here’s the text:
##auto.Text##
Like i said, the documentation doesn’t explicitly say you can do this, but it also doesn’t say that it won’t work (that i can find). I can’t remember if i’ve ever tried this before, but it’s worth a shot.
