Use __cloud:UserId in a Macro

[jonriddle]

I have some fairly long running analytic apps on my private gallery.  We have many different users who will run these apps and I would like to send them an email when the app is complete so that they don't have to keep checking back for results.

I came across a few different posts that explained how to use a text input named __cloud:UserId to determine the user id of the person running the app and then to query the MongoDB for that user to retrieve their email address.  These posts were very helpful, as I do have it working in my analytic app.  However, I tried putting all of this into a macro so that I didn't have to copy/paste every time I needed the current user's email address.  Unfortunately, the __cloud:UserId text box does not seem to work if it is in a macro.

@jonriddle Great catch. This would be really useful if it was available in a macro.

Being able to get Gallery Run details in a macro is very import, user, email, run id.
