LGTM. I know Jack wanted this as well

[jackzampolin]

I like this! 👍

[jackzampolin]

Can we hold off on this one please? I've had to make the same change in #2018 so this would be redundant.

[alexanderbez]

@jackzampolin sure. You can close this PR. Looks like #2018 needs a good rebase though

Closing in favor of #2018.
