Allow Dynamic Date Option in Introduction window content

MHansen

Please consider creating an option for Instant Apps that allow for dynamic date options in the introduction window. It would be beneficial for users entering the app to be able to see something like "Current as of: MM:DD: YYYY". Currently, this has to be done manually, which is not efficient.

@MHansen Currently, you can write a notebook (run the notebook every day or hour) and update the json of the introduction window in the app. to update the date to the last edit date value.
