Explain the problem as you see it
There is no way to post to Trans Today node using external apps with API.
Why is this a problem for you?
I need to go through Inbox to move them to Today and remember about that it’s there.
Suggest a solution
Universal ID for “Today” (maybe also + and -X relative number of days) or other way to allow integration with the final gessler of posting content into specific relative Day Node.
