Status Icon for Assets - How to create a custom status for Unreal Assets (Similar to Source Control)?

Hi guys,

I have a question to you. I believe everyone know what is Source Control so I wont focus on that. When we are connected to Source Control we can see status in top right corner of the actual asset.

I wonder if there is a way we can add additional icon in bottom right corner for personal purpose? Where I can look for that? Any suggestions?

I was thinking about writing a plugin for that but I have no idea where to start. I will really appreciate any help!

Thanks,
Bart
