Add Subject Lines to Snippets

[BSchultz6]

Make it possible to apply Subject Lines to snippets

Yes, Subject line in snippets, and with 'personalization' features too, like in the text box. Please

This would be amazing!! Looking through all suggestions now hoping someone had previously suggested this. 
It is frustrating having to apply the subject line each time when the purpose of a snippet is to prefill for you.
