hi, is it possible to collect two levels of map keys in the process of navigating to a third level in a nested map ?

so, i have {:a {:b {:c :d}}} and i want to map/`transform` over {:c :d} but while retaining the context [:a :b].

(specter/collect specter/MAP-KEYS specter/MAP-KEYS) gives the error "Don't know how to create ISeq from clojure.lang.Keyword".

thanks in advance!
