Bulk Create Connections via workflow

Hi all,

I have a scenario in which I'd like to bulk create Connection records using workflows, and I would appreciate any advice on how best to achieve this.

My scenario is as follows:

1. I have a Parent Entity A which has two "child" Entities B and C

2. When I create a new record in Child Entity C, I would like to create a connection from this record to each of the records under Child Entity B that share the same parent record in Entity A

Can anyone advise on the best way to achieve this?

Thanks!
