Noting a change to Pass/Fail on home school transcript

I am a home schooling parent in Texas and I changed 2 home school courses to pass/fail during COVID-19 because of family and academic issues due to the virus. Does anyone have advice for how I can note this on my children’s transcripts?

My idea was to put an asterisk next to those courses and then a note at the bottom. However I am not sure how that note should be worded.

I tried to contact the home schooling association and have received no response. I can’t find any examples on google, probably because school districts are still figuring this out themselves.

Appreciate any help, thanks!
