Select part of a message

### Your use case

#### What would you like to do?

I'd like to be able to select + copy only a part of a bigger message

#### Why would you like to do it?

In order to extract a smaller part of a bigger message and not having to copy the entire message to a separate text editing app in order to do that

#### How would you like to achieve it?

By pressing and holding on the text of the message and using the Android text selection handles to pick which part I want to copy

### Have you considered any alternatives?

Copying the entire message into another app and making the selection there, but that's cumbersome
