Referencing journal issue months using APA 7th edition

I had an interesting question on APA 7th edition when referencing a journal which had not specified an issue number, but instead has a month. The reference was provided as:

Byrd, H., Ho, A., Sharp, B., & Kumar-Nair, N. (2013). Measuring the solar potential of a city and its implications for energy policy. Energy Policy, 61(October), 944-952. http://dx.doi.org/10.1016/j.enpol.2013.06.042

I looked in my APA manual, but this use of month over issue number was not mentioned. So I went to the blog of APA Style, and asked one of the APA elves, who replied:

If your journal uses the month as its issue number - October in this case - then you should format it like this: 61(10), [u]sing the numerical equivalent of the month provides a clear "number" for your issue (Adams, 1 October 2019).

So the resulting reference reads:

Byrd, H., Ho, A., Sharp, B., & Kumar-Nair, N. (2013). Measuring the solar potential of a city and its implications for energy policy. Energy Policy, 61(10), 944-952. http://dx.doi.org/10.1016/j.enpol.2013.06.042

Easy when we know how.
