Inserting a reticle style scale bar on an image?

Is it possible to overlay and embed a reticle style scale bar over an image? Are there existing plugins that can easily achieve this? The closest I found is the Grid command via Analyze>Tools>Grid. If such feature doesn’t exist, is it possible to request it?

See attached screenshot as an example of what I mean. This screenshot is from Olympus Stream software. It has a feature to overlay a digital reticle and adjust various settings for it. However, it is silly that the software doesn’t actually embed this reticle scale bar on the saved JPEG file.
