Hello Make Community 
I’ve built a scenario that syncs Hubspot Line Item Owners to Notion Project Assignees. The flow looks like this:
Hubspot Deal → Find associated Line Items → Get Line Item Owners → Push to Notion.
It works well in testing, where I’ve been using the “Search for CRM Objects” module to simulate changes. But now that I’m getting ready to go live, I want to avoid polling everything constantly — it seems inefficient to call every item each time just to check for changes.
My question is:
What’s the best trigger to use if I only want to watch for updates to Line Items associated with a specific Deal?
Should I use “Watch changes” on Deals, or is there a better way to watch changes to Line Items directly (especially ownership changes)?
