Ancillaries

Is it possible to add effects to ancillaries? Like adding influence to the aged_retainer as in the example below. I tried to add this as a test but I did not see any change in influence in the general who had this ancillary.
Thanks in advance.

Example from export_descr_ancillaries.txt:

Ancillary aged_retainer
Image older_man_ancillary.tga
ExcludedAncillaries evil_mother-in-law
ExcludeCultures barbarian
Description aged_retainer_desc
EffectsDescription aged_retainer_effects_desc
Effect Management 1
Effect PersonalSecurity 1
Effect Influence 6

You also have to edit the export_ancillaries file in the text folder, or the bonus won't appear in the description (although it should have an effect on your general)

dunno why but sometimes the command stars and such can differ between on the field and in a city...
