Yes, but provides something like:

--8<---------------cut here---------------start------------->8---
 (guix store)
 (guix derivations)
 (guix packages))
(define (build-packages packages)
  (with-store store
    (let ((builds (map (lambda (package)
                         (package-derivation store package))
      (build-derivations store builds))))

(define (build-package package)
  (build-packages (list package)))
--8<---------------cut here---------------end--------------->8---

Because otherwise, you need to know "package-derivation" and
"build-derivation" and where they are (I run 'ag' or 'git-grep'
to find them which is not handy).  And for example, I knew it was
possible but it was not "obvious". :-)
