So far I can interpret your screenshot this method works for region automation, not for track automation. The fader can be recorded on instrument tracks (as a region) or be a track with regions itself. You can try to move the written region automation to the track but I have never seen this actually working. Normally I use one or more controller tracks for such tasks.
There is however a solution, with a transformer set to "Split Track Automation" and clever routing. Go to John Pitcairn's Website:

Scroll down to the paragraph "External/internal midi CCs to track automation", download and study this small but universal patch and use what you need.
Another method is to send your onscreen fader out to a MIDI port, an IAC bus for example. Must be CC or another standard MIDI event. Then it comes in again as "external MIDI" and you can map the events to your plugin(s) with Logic's Controller Assignments. Processing possibilities are limited this way.
But when I look at your screenshot I would rather go for one or a couple of tracks with region automation. Editing in HyperDraw isn't too bad, curves are available.
.. i have minutes left in the studio...
Complex MIDI processing with automation, neither familiar with the environment nor with Logic's parameter control but only minutes to do it? This will definitely not happen. You need hours, days, weeks or months depending on the size and functionality of the patches you want to build.
