Is there a way to know if a dispatch command opens a dialog?

Possible hack solution:

Create a thread_local bool flag, which is cleared on entry to the dispatch logic, and is set by the create-a-dialog logic.
On exit from the dispatch logic, check the flag and return true if the a dialog was created.

Note that there is more than one way to create a dialog, so this flag would need to be set in a handful of places.
