Shortcut to tell Discord what I'm sending is part of a new message group

You can adjust space between message groups, but if I'm replying to many different topics at once, Discord makes it all one message group. 

I.e. — There is no visual way to send consecutive messages while keeping different topics separated. Instead it is just one giant wall of text. 

Is there a shortcut key to get that extra line spacing even though I haven't paused between sending the two different messages? Some way to tell the app it's a new message group. 

What is the duration necessary to wait before Discord decides the next messages are part of a new group (new topic)? 

As a workaround I've been adding "headers" in **bold** but this is only half helpful because there are various topics that should be separated message groups under each heading. 

My current secondary sub-topic workaround to create visual "message groups" has been to add an m-dash before each new topic. This is still visually chaotic, but somewhat helpful. 

See below — each m-dash'ed message is a new message group (new sub topic). Without the m-dash there is no spacing between the messages and it looks like wrapped text continuing in the same subtopic. 

Happy that Discord is *almost* perfect for replacing email. 

Hopeful there is a real solution to creating your own message groups without literally waiting for time to pass before sending the next topic's messages.
