Screenshot / Code Snippet
##UserId##parameter is treated specially for users who are logged in. If they have an account on the target site that shares the email used in their Data Explorer account, their user ID on that site will be automatically populated.
However, this doesn't always work. This script aims to fix that, and as a bonus, it will autofill
AccountId parameters with your network account ID for cross-site queries.
Developed and tested with Tampermonkey on Firefox; somehow it doesn't work with Violentmonkey.
