Hello. I'll revive the thread. Maybe it'll help someone else. Yes, it is very easy to design any indicator. Go online and find a short video of what you want to design. Open the video in VLC program and save 16 png format images from the video. You can do this automatically in VLC.
You can get PNG format images from the video you play in settings/advanced settings/filters/scene filter. Define these 16 images as custom in the section you will design later.
