Please bring back channel access in the mixer

I miss the way instrument channels were handled before:
If you had a violin, you could click on an arrow to get equal access to the pizz and tremolo sounds.
Now, it's all done automatically behind the desk as it were.

In many of my scores, I used and abused trumpet, bass, and synth parts to create multiple guitar and keyboard lines. Once I discovered this method, I never used Change Instrument again.
Many instruments without a growing mixer, perfect.
Please bring that back.
