A clumsy suggestion that maybe could help, as I don’t see how the PLE will be of any help for your inquiry anyway…
- On the involved MIDI/Instrument track, if there isn’t any, create a “dummy” part with the pencil tool.
- [double-click] on it to open the Key Editor
- If no controller lanes are visible, use the Controller Lane Setup menu and the Show/Hide Controller lanes option.

- Set all the different controller lanes as wanted.
- Using again the Controller Lane Setup menu, create a preset with the Add preset… option.
- Close the Key Editor.
After this go in the Edit > Key Commands window and create a Macro that will contain the following commands :

Explanation : when creating a controller lanes setup preset, and if there isn’t any one already existing, it will be available as a key command with the MIDI > Controller lane Setup 1. Otherwise, we have to adjust the preset number accordingly (up to 16). This macro applies the Controllers as wanted in the Key Editor. We then can draw or record the CC needed.
At a second stage, another macro needs to be created to make the MIDI CC extraction and display in the correct size the automation lanes :

Known limitations :
- The second macro will fully work only if the key editor (or any other window having focus, I guess, something to test…) is closed and you are in the arrange view. Otherwise, only the extraction will occur.
- If you need more or less CC lanes, you’ll have to add/remove instance(s) of both Navigate - Add Down and Zoom - Zoom in Tracks commands in the macro, accordingly.
Beside this, I have tried to use the Zoom preset 1 → 5 key commands for your need, after creating a Zoom preset : sadly, it doesn’t work, at least, on my end, and I’m still trying to figure out how to affect a user created zoom preset to these. Overall, your inquiry show all the limitations of Cubase PLE/Macro implementation, IMO.
So, the whole thing is not perfect, but maybe it could help, somehow. Just hope that someone will find a more efficient way of doing…
Alternately, and if you need to record the CC messages in “real time”, you can use the MIDI Controller Automation Setup window. In the Record destination column, changing it to Automation Track for the involved CC numbers allows you to make appear the automation lanes directly while recording, provided that you have activated the Write button in the track header.
EDIT : changed the whole process, with two macros instead of one…
