Hi @lincolnlemos
Could you please tell me why do you need to change the field group three times a day? It’s an unusual way to use ACF and it will be hard to maintain as you have a lot of blogs.
If you want, I believe you can also use the Local JSON feature. You can set the loading path to your parent theme so that it can be accessed from your other blogs. This page should give you more idea about it: https://www.advancedcustomfields.com/resources/local-json/.
I hope this makes sense 🙂
