What I would do:
- In your Properties table, add a Multiple Files column. This is an array column that will hold an array of “Not Interested” LeadIDs
- Assuming that your Property Details screen contains a Collection of Leads, configure an Item Click action on that Collection that adds the LeadID to the Multiple Files (array) column.
- In your Leads table, create a Relation column that matches the LeadID with the Multiple Files column in the Properties table
- Use that relation as a filter on your Leads collection - only show rows where the relation is empty.
