User ayanamsha correction in addition to the ayanamsha chosen

Hi Ernst,

Is it possible to have a custom ayanamsha correction in Kala supplementary to the chosen ayanamsha? 

For instance, I find that the True Mula (Chandra Hari) ayanamsha best mirrors the horoscope my family astrologer produced at the time of birth, but three planets are a few degrees off, which means they end up in different sthaanas. I'd like to customize just those three planets and attempt to get them into sync with my actual paper horoscope at birth by tweaking the ayanamsha through minor corrections.

Is that possible?
