I need a date with only Month and Year

I have a Expiration Date area that needs to be like this EX. 10/20. I cannot find out to eliminate the day part of the date element. 

Though we do not have anything specifically that only allows month/year, there are a couple workarounds in the following thread that may be of use:

The screenshots are a bit outdated but the process is still the same.
