The task is to set the dog icon and hashtag in voice dictation on android. Who faced?

Question

Android

In general, I have a task manager and it is very convenient to dictate some tasks by voice, the manager himself recognizes the date, but projects and tags are actively working for me.
When I dictate - tomorrow at 21:00 to read a #entertainment book (tag) @read (project) , I can't get gooogl's dictation to put the # and @ signs. At the same time, periods, commas and other punctuation marks work with a bang.
Two questions:
1) Is Google's dictator able to do this? And if so, how? Is it possible to teach it, set it up? ..
2) If another recognizer can do this, tell me which one.
Thanks to!
