We would like to pursue creating our own online help documentation that is customized to our users' needs and based on the controls that are set by our adminsitrator. Is it possible to edit the endpoint for the "Help" link at the top of the Tableau page that currently links to javascript:callHelp('/v_70001202151930/help/en_US/','projects.htm')?  If so, where can I find the details about how to do that? Thank you.
