Better sub block handling

Hello.

In IQANdesign i wish it was easier to handle Function groups. I want to keep my Application Logic clean and easy to follow, by putting channels in subblocks / sub functions groups.

I find the current Function groups very difficult to handle. I wish I could drag and drop many channels into the Function blocks without having to think about referenses, creating Function group inputs etc. 

The "Move up" function makes it a little bit easier, but still I have to take all channels one by one and use the "Move up" function on them. And why are there no "Move up" for outputs of Functions groups? 

The subblock should be purely visual, not add or remove any functions. Similiar to how it works in Simulink. 

I could make my logic much easier to follow with this possibility.
