From GameWatcher: “Paradox has revealed that Crusader Kings 3’s Patch 1.5 will introduce a coat of arms designer to the grand strategy game, giving players the opportunity to customize their realm’s heraldry.

Detailed in today’s dev diary 71, CK3’s coat of arms designer will launch with options to start customizing one from scratch or adjust an existing coat of arms. The former offers the most freedom while altering a historical coat of arms is likely quicker but comes with a number of limitations.”
