Only do this if you really know what you are doing and know specifically why you are going to do it.
ScreenSteps stores a record of the Zendesk ID of every article you publish from ScreenSteps to Zendesk. That ID is the only way ScreenSteps knows which article to update in Zendesk. ScreenSteps does not decide which article to update in Zendesk based on title, only based on the ID that ScreenSteps stores.
The main reason to use this feature is to connect an existing ScreenSteps article to an article that already exists in Zendesk. This allows you to have ScreenSteps update the existing Zendesk article without changing the Zendesk URL for that article.
