Use main app icon also for shortcuts

I’d like an option to use the main app icon also for the app’s shortcuts. For instance, I use TickTick as my task manager, but prefer to open it via a custom designed shortcut to show tasks for my “Next 7 Days”. I can change the icon for this shortcut into many different varieties, just as for the main app, but not to TickTick’s original icon - which is what I want.

Suggestion: for shortcuts, in addition to “Reset to default”, also add an option to “Use main app’s icon”.
