On SageMath Cloud, how can I use Python 3 notebooks?

I'm using the fantastic SageMath Cloud service to remotely collaborate with a partner. In particular, I'm using IPython notebooks. Unfortunately, the language seems to default to Python 2; I would prefer Python 3.

SSH'ing into my project, I can see that IPython 3 is actually installed. Is there a way to coerce SMC into using Python 3 for notebooks?

I have tried the instructions mentioned in the FAQ, i.e.,

ln -s /usr/bin/python3 ~/bin/python
ln -s /usr/bin/ipython3 ~/bin/ipython

While this works for invoking Python from the SSH commandline, it doesn't seem to affect the kernel used by IPython notebooks created from the web GUI.

Once you open an IPython Notebook on SageMathCloud you can switch the kernel to a variety of choices, including Python 3. To do that, use the 'Kernel' menu, then 'Change kernel', then 'Python 3'.

Switching to the Python 3 kernel in the IPython Notebook on SageMathCloud is discussed in this discussion the sage-cloud mailing list.

Is this what your question is about, or are you asking how to make that choice the default when you open a new IPython Notebook on SageMathCloud?
