Mail Importance or Priority Rule

Is there a way to create a rule or otherwise change an email’s importance / priority (Low, Normal, High)?

I want to love this app, but there are a couple of minor annoyances/dealbreakers for me. eM Client has extra features that I need There are a few key Outlook features that I depend on… The Calendar in particular leaves a lot to be desired! And lately, the app has been crashing even when I’m not using it :frowning:
