Hi!

I am creating a database of booking, where I need the ability to link older versions of objects (hotels and their data) to history of bookings - at this moment, I am successfully capturing whole history using:

Object::add_extension('PhysicalLocation', 'Versioned("Live")');

This works well - however, is there a way to "force" also all relations (which are all Versioned too) to return with a version corresponding to that object? My idea of the "restriction" is that the relevant record should be the latest found in version history which still has modified date older than (or equal to) the parent fetching it - this would ensure that I would always get a snapshot for that time instead of latest (and no longer relevant) data.
