Re-generating model file with textx

I'm new with DSL and I'm not sure if it's possible the tasks that I want to do with textx:

1. I already have language description textX (ex: hello.tx)
2. Load an initial model file for this language (ex: example.hello)
3. Edit the currently loaded model.
4. Re-generate a new model file (new_example.hello) with the additions.

Is it possible to do it with textx?

Thank you

Programmatically changing the model and then persisting back to the textual syntax is not supported at this time in textX.
