I know that I can map specific SD cards to specific mountpoints in macOS (see How to mount certain SD cards to a specific mountpoint in El Capitan?).

However, is it possibile to map a specific SD reader to a specific mountpoint, regardless of which SD card is inserted?

I have 4 SD Card readers, physically labeled 1..4 and I would like any SD card inserted in Reader #1 to be mapped to, say, /media/reader1; any SD in Reader #2 to be mapped to /media/reader2; and so on.

(These readers are same brand, same model - there might be no way to tell them apart, I don't know, but if there isn't, I could acquire different models if that helps. Also, these readers are disconnected and reconnected daily to a laptop, it's not a static setup, although they are the same readers every day. If useful, each reader can be reconnected to the very same USB port, if these can be tracked by USB port. Also, these readers can sometimes be connected to a USB hub).

Any way to do this in macOS (specifically high sierra)?

Below, the result of system_profiler with two of these devices inserted. The only visible difference seems to be the "location", or USB port.

 $ system_profiler SPUSBDataType
