Thanks for your answer.

I replied to Marcel's message before reading yours so we could hopefully 
merge into one message thread.

One specific point to your answer: the device alias is certainly 
available (and in this case would satisfy the use case of 
manually-select-by-alias, so to speak) but that doesn't seem to scale 
well if you would also like to use other criteria (for example, to 
filter some devices depending on their icon, available services, etc.).
