Describe the feature

Feature: Support for marking a collection/item as completed and unnecessary for all fetch updates.

Suggested implementation: While editing collections have the ability to set a collection as - "do not fetch updates during all fetch". This should exclude the collection when trying to do a full library updates fetch.

Feature Motivation

Use case: If user is using a collectiion for long term "storage" for completed items. These items are completed and their fetching is unnecessary unless the user specifically wants it.

current solution: Current solution to avoid unnecessary fetch is to individually fetch collections, but if the user is a heavy collection user this increases users needed presses.

Impact: small ux improvement for certain users.

Reasons not to implement: If using collections as described is not an intended use case
