Is it possible to make a custom renderer for StringTemplate without using STGroup's?

Question

I'm trying to use StringTemplate to be able to parse some configuration file inputs, and was wondering if it was possible to register a renderer without using STGroup.

Example (but the registerRenderer method seems to be missing from the library):

ST myST = new ST("Hello, <thing>!");
myST.add("thing", new Thing());
myST.registerRenderer(Thing.class, new ThingRenderer());
return myST.render();

Actually after posting this, the answer came to me.

STGroup myGroup = new STGroup();
myGroup.registerRenderer(Thing.class, new ThingRenderer());
ST myST = new ST(myGroup, "Hello, <thing>!");
myST.add("thing", new Thing());
return myST.render();
