Is it possible to use typerefs as build args?

[rudfoss-rr]

I have several targets that build containers in my project and some depend on each other. I can use the tags option to specify that the containers will be tagged with the branch name which is great when building in a feature branch, but is there a way to use the same value in the build-args to tie multiple container images from the same branch together?

Something like this:

project.json:

{
	"executor": "@nx-tools/nx-container:build",
	"dependsOn": [
		{
			"projects": "@project/source",
			"target": "prebuild"
		}
	],
	"options": {
		"build-args": ["BASE_BUILD_TAG='type=ref,event=pr'"],
		"metadata": {
			"images": ["test-project"],
			"load": true,
			"tags": ["type=schedule", "type=ref,event=branch", "type=ref,event=tag", "type=ref,event=pr"]
		}
	}
}

Dockerfile:

ARG BASE_BUILD_TAG=latest
FROM base-build:$BASE_BUILD_TAG AS buildbase

Or am I going about this the wrong way maybe? I'm still relatively new to containers.
