If not mistaken, the current version does not allow to augment the non-linear panel LP with IV (at least there is no option to specify the instrument). Would it be a relatively straight-forward task to implement this (i.e., with already having the existing routines on non-linear LP and the IV setting for panel LP)?

Any guidance would be of help.
