Prefilter with relation

[Biromain]

Sorry, i have look lot of issues but not found any way.
FYI: Scopes are in Mapper.
I search to filter result with relation state without get all parents and loop on it.
Like :
$mapper->get(x)->childrens->published()->location->geoValid()
or
$mapper->get(x)->childrens->published()->geoValid() but geoValid filter on relation.

I have tried with relationName.field in parent scope but generate table.relationName.field.

Regards,
