Synchronize 'grp' in favorite effect

Hi! First of all, thanks for everything WLED does. What a cool project!

I have 3 controllers (esp8266) synced up with one being the main driver. I setup some effects favorites and would like one of the favorites to have a larger group (grp) value. I edited this on the Favorites page and saved it. However, when I switch to this favorite the 2 other controllers just play the effect without the larger grp setting. How can I share this to the other controllers?

Here is the JSON from the favorites preset API command field:
