Need to add fields to PD Infotype 1610 in 4.6C

[shell_hr_abap]

I need to add a few fields the contry specific Infotype 1610 (US Job Attirbutes). This Infotype does not implement the standard MP161000 module pool that will allow me to create a subscreen and activate it in table T582C. I tried using transaction PPCI to extend the infotype. I created the include structuer, ZP161000 module pool, subscreen (200) etc..., no go.(?) Trasaction PP01 seem to be calling the view V_T5U13_B. This view does not use the "standard" PD infotype table HRP1610. Furthuremore, the view does not contain any include structures that I can use.

Anyone with any suggestions as to how I might go about extending this Infotype.
