I'm using a third party tool (AWS Quicksight) to embed a dashboard into an SFDC ISV application. This tool requires all domains where the dashboard is embedded to be whitelisted (not whitelisted in SFDC but directly in Quicksight). So each time I have a new customer who uses my application I've been asking them to copy their URL and send it to me so I can whitelist it. An example of the domain I'm whitelist is "https://MYCOMPANY--four-cast.naXX.visual.force.com" (where "MYCOMPANY" and "XX" are unique to the org).
Is there a way for me to whitelist all SFDC domains/sub-domains?
