Feature request: Setting internal window name on start

As I see now, terminator doesn't set WM_WINDOW_ROLE window property. I just want to say it is very useful when managing different terminal apps. Window manager can easy identify specified app mnd manage it automatically.
For example, in urxvt there is a console argument. Something like
$ urxvt -name "myprettyapp"
results setting WM_CLASS property to
WM_CLASS(STRING) = "myprettyapp", "URxvt"
(property checked with xprop)
I ask you to add such a thing to terminator. It will make me happy ;)

Corrected: I fount forcedtitle option -T but it changes window title permanently which is not great
