In my particular case, I have a Blendshapes node for a character, with around 100 shapes.
The channels were named using the Update Channel Names From input button, which actually doesn't change the channel names but creates aliases for them.
Problem is that when I create the interface for the character and promote the Blendshape channels, the Aliases are not coming with the channels (see screenshots below).
I guess there is a Python solution for this, but in character scenarios this should be a pretty useful feature.
