Different custom images as marker in layer

[Ste-denko]

From the documentation and demos I can see that only one custom mgl-image can be used as a marker/icon-image per mgl-layer, is that correct?
If not, how can I achieve to have different marker/icon-images in one layer.
For example:
I have one layer that shows 1000 items in the map and some of them should have marker/icon A, some marker/icon B and the rest marker/icon C.

Thanks a lot in advance.
