No, I don't think so.
http://git.savannah.nongnu.org/cgit/nmh.git/tree/uip/annosbr.c#n377
shows -text's argument being written to the field, preceded by the field
name, once for each line-feed-separated chunk.
You could cheat and consider if you know a character won't occur in the
file which you could use as a placeholder for the line feed.
$ echo a: 1 >1
$ anno -nodate -component subject -text $'hi foo\r bar\r xyzzy' +. 1
$ sed -n l 1
subject: hi foo\r bar\r xyzzy$
a: 1$
$
$ sed -i 's/\r/\n/g' 1
$ sed -n l 1
subject: hi foo$
bar$
xyzzy$
a: 1$
