This is awesome, if you can do the CLA real quick I can merge it in.

When I click the CLA then I get: “You have agreed to the CLA for blankly-finance/blankly” but then the commit page does not look to me like it is done. If it's not done let me know.

Oh interesting it looks like CLA assistant isn't updating

Merged & released in the mainline package, thanks for this pr.
