Combining revisions from two sources

[chepati]

We have an application that deploys a helm chart from source A and values file from source B. The helm chart's application has its own version (let's call it revisionA) which is half of what we want. The other half is the sha1 of the git commit (let's call it revisionB) of the values file from source B.

We want to concatenate the two revisions into a string "revisionA-revisionB" and have ArgoCD add it as a label (or annotation) to every pod this helm chart launches.

Any suggestions how to do this?
Thanks.

I would like to add a context here

We are using latest (close to latest) ArgoCD v2.12.4. Multiple sources tab was introduce. We do have source A for helm and source B for values. We wanted to pass ArgoCD build variable into our pod - ARGOCD_APP_REVISION
https://argo-cd.readthedocs.io/en/stable/user-guide/build-environment/

What it seems to be in logic of ArgoCD
https://github.com/argoproj/argo-cd/blob/master/reposerver/repository/repository.go#L408
when 2 revisions are in use - he uses helm revision instead of sha

Can this be looked into and some solution be proposed?
