Setting advanced (for me) reminder on subitems columns

Hello friends,
I need your help with building a workflow.
I want to get notified after some days from actual date by it’s a bit advanced as it’s all in subitems.
On my board I have:

The actual date and I have number of days.
I want to get a reminder once 50% of the time has passed.
I add a formula column to calculate {Days}/2 so I get the number of days I want use for the reminder.
I also manage to calculate the reminder date and set it in Formula column, the thing is it doesn’t support reminders.
Now, I can’t use this automation as it doesn’t support neither subitems not formula columns:
automation
I can’t use General Caster as it doesn’t support subitems.

I tried to do it with Zapier but couldn’t figure out how to do it.

Any suggestions?

Thank you.

Do you know if it’s possible to build the same workflow with Zapier instead of “Make”? (Our team works with Zapier.

@Hezibo

Probably. I no longer use Zapier. Make is better in my opinion and about half the cost.
