How to get extid in e.g the albums list using the SqueezePlay interface

That is:
https://wiki.slimdevices.com/index.php/SBS_SqueezePlay_interface

In the Squeezer we would like to implement an visual identification of
which service an album belongs. This to be able to distinguish them,
because the albums lists returns albums from both local music as well as
any connected music service.

However I can't find a way to get that information using the SqueezePlay
interface.

Is that even possible, or is there an alternative?

To explain further I'm aware that you can get the extid from the
"artists", "albums" and "titles" queries. We don't hardcode these in
Squeezer. Instead we request the home menu like this:

Code:
--------------------
    ["menu","0","512","direct:1"]]
--------------------

and use the returned results to go to each menu. For the album list this
would be something like:

Code:
--------------------
    ["browselibrary","items","0","512","mode:albums","useContextMenu:1","menu:1"]]
--------------------
