TextCommand in build system?

[gregor.hoch]

Is it possible to use a TextCommand in a build system directly? Of course, I can define a window command

class RunTextCmdCommand(sublime_plugin.WindowCommand):
    def run(self, cmd):
     view = sublime.active_window().active_view()
     view.run_command(cmd)

and use that as the target argument

{
	"target": "run_text_cmd",
	"selector": "...",
	 "cmd": "my_text_cmd"
}

That works fine. I was just wondering whether there is an easier solution circumventing the WindowCommand. Thanks!
