Some may be interested in this scholarly paper by Ola Wikander:

“Go Out from Your Sign???: Rashi to Genesis 15:5 as a Reference to Astrological Primary Direction – Its Background in Rabbinic Literature and Parallels in Abraham bar Ḥiyya

Thank you for sharing this paper Martin,

In Section F, Ola says

"An even more interesting - though speculative - possibility would be Rashi reading the Talmudic reference to moving Jupiter from the West to the East not based on astrological calculations fitting Palestinian or Babylonian geography but in the light of the latitude at which he himself was living (Troyes in modern France). That is, it is far enough north of the equator to allow the possibility of a planet on the Descendant taking only about 120 years to move to the Ascendant in Primary Direction (viz., given the idealized case of a native being born with the exact beginning of tropical Capricorn on the Ascendant).30Thus, if Rashi knew something of Primary Directions in his own milieu, the moving Jupiter providing an heir in the Talmudic passage may have seemed less of a miracle. This could thus suggest not only a knowledge of the technique itself but also a reflection of Rashi's own geographic situation as a basis for his interpretation."

It does suggest that by moving to a different location you can change the activation time of a Direction. Similar to where you are on your birthday as opposed to your birth location for a Solar Return.
Have you seen cases like this or can we stick to the natal?

Thank you,

I'm not at all sure the author meant to attribute a doctrine of relocational astrology to the medieval commentator. And no, it's not something I have seen myself.
