Ability to directly copy resultant text, rather than exporting a .txt file

Clicking Share > txt brings up the text file as an attachment (to put on an email, WhatsApp message, etc)

This introduces an extra step of opening it in a notepad app, selecting all, copying and pasting

Is it possible to just display the text file with a "select all" button instead? It could still be saved in the background, it's just fewer clicks

Thanks
