To handle many versions in an automated way, I once wrote this: 
https://gitlab.com/methuselah-0/guix-cigmon/-/tree/master

It's a schedulable script that will check for updates in certain git 
repos (specified branches if you want), and create inherited package 
versions for the new commits which it can commit and push to a guix 
channel repository. Probably doesn't solve your problem completely, but 
might be useful.

Example contents of a new file python-nbdev-org-babel-rev.scm with 
versions of python-nbdev-org-babel, automatically added to a guix 
channel:

(define-module (python-nbdev-org-babel-revs) #:use-module 
(python-extras) #:use-module (guix packages) #:use-module (guix 
git-download))
(define-public python-nbdev-org-babel-4f195e9 (package (inherit 
python-nbdev-org-babel)(properties '(("generated-by" . "cigmon")))(name 
"python-nbdev-org-babel-4f195e9")(source (origin (method git-fetch) (uri 
(git-reference (commit "4f195e915eefe5cd4deec3c6aea27e4b61233f33")(url 
"https://github.com/methuselah-0/nbdev-org-babel.git")))(sha256 (base32 
"0ayfxnw1s9rzs1qpqqyqwhf21xk6g8psffsqzfvvl0w5k1j88dqn"))))))
(define-public python-nbdev-org-babel-66079a5 (package (inherit 
python-nbdev-org-babel)(properties '(("generated-by" . "cigmon")))(name 
"python-nbdev-org-babel-66079a5")(source (origin (method git-fetch) (uri 
(git-reference (commit "66079a59aa9ee5e4479bdce597aac0f42f7fb565")(url 
"https://github.com/methuselah-0/nbdev-org-babel.git")))(sha256 (base32 
"0krdpc6zbdljriw6s80g08fywy0d1nq8wi3q07v3qs0b6rfz68n4"))))))
(define-public python-nbdev-org-babel-master (package (inherit 
python-nbdev-org-babel-66079a5)(name "python-nbdev-org-babel-master")))


This way you can pin some packages to have an input like 
mypackage-<1234567>

Would that be useful?
