Pythonista Lab reset environment??

[ericm301]

In Pythonista, while viewing the console, a long press on the Clear button would popup a dialog that asked me if I wanted to reset the environment, essentially clearing all the console or script created objects and starting with a 'clean slate.'
How do I do the same thing in the Lab? The only thing that I've found to do it successfully is to FC the Lab and reopen. This doesn't sound ideal.
Any suggestions? Am I missing something?

get_ipython().reset() does something similar in Lab.
