Welcome to Fibery!
I would use Periods for something like this. You can set the sync frequency to daily, then it just syncs once a day.
If you don’t include the “Relative” field, and set it up with no semantic naming, it not use many entity syncs. If this doesn’t work, please share your set up and what’s happening
You can then set up the relations similar to how I did it here: Weekly view using relations, automations, and board view
It’s similar to auto-linking, but then also allows drag and drop.
