+1 for this, we had a potential educational institution using another brand looking to refurbish; they wanted “like for like” in features. This is one of those features; they stayed with the existing brand.
The feature aligns with having custom site maps (like floor plans) for showing WAP locations and devices to overlay on top with.
We realise there is a lot more to the development of this than it appears on the surface, and acknowledge the efforts of the Peplink Engineers 
Happy to Help,
Marcus
