Making FLS portable

Hi guys

I know you dont support that etc...
Ive been using for many many years a launcher I wrote (in nsis) to make FLS and vst plugins portable. It works perfectly.
I just updated to fls12.9 (from 11), and managed to move the IL/shared folder to fls own folder, as it should be to me, modifying the regkey you kindly use.
Still theres this annoying use of mydocuments folder and i dont want that, is there any way to get rid of it / set its location ? It seems to be hard coded in the exe, i dont see any entry regarding this.
Thank you very much.
