Is it possible to create a trigger that allows for deleting/editing all items associated with a specific field?

[Phil_Clark]

I’ve got a large database of clients and would like to allow for bulk editing that associates a specific field (example: company name) with all parties that are affiliated with that field. As an example, if 20 people in my database of 6,000 all work for Company A and that company moves, is it possible to change the address for all 20 entries all at once?

Is it also possible to delete multiple entries in bulk? Using the same example as before, if Company A closes, could I delete all entries associated with it in bulk?
