Is it possible to have defmutation errors also update the ::p.core/errors key (similar to defresolvers)?

Copying @wilkerlucio's answer from Slack for more visibility:

you can with a custom ::p/process-error:

(def mutation-parser
  (p/parser
    {::p/env     {::p/reader               [p/map-reader
                                            pc/reader2
                                            pc/open-ident-reader
                                            p/env-placeholder-reader]
                  ::p/placeholder-prefixes #{">"}
                  ::p/process-error        (fn [env err]
                                             (if (= :call (-> env :ast :type))
                                               (p/add-error (-> env
                                                                (update ::p/path p.misc/vconj (-> env :ast :key))
                                                                (dissoc ::p/process-error)) err))
                                             (p/error-message err))}
     ::p/mutate  pc/mutate
     ::p/plugins [(pc/connect-plugin {::pc/register mutation-error})
                  p/error-handler-plugin
                  p/request-cache-plugin
                  p/trace-plugin]}))
