Oh sorry, forgot about that request already 
I found out that my shortcut tool using dblue’s pattern resizer algorithm is already a quite easy way to get more detailed automation while recording:
Just use one of the expansion shortcuts, which cause a temporarily expansion while recording, for automation recording. After disabling recording, the automation will be properly shrinked to much more fine resolution.
You can set the temp. LPB even higher in the script.
The only thing which is missing now in the resize algorithm is to temp. patch all synced LFOs and delay devices.
