Fix bullet points & insert provided keyword strings (Amazon.com)

The task:

In Amazon Inventory delete two specific bullet points from the product details – from Parent and ALL Children/Variations of the product. If the specified bullet points are not present – nothing needs to be done in that listing.

In the Keyword section (Parent and Children/Variations), if the Keyword field is empty or has only one or two words – paste a relevant keyword string (from a small list of keyword strings provided). If there is already a long keyword string in the Keyword field – nothing needs to be done in that listing.

Monotonous, but very easy task.
