ACR Tasks in Azure DevOps/Pipelines

**What is the problem you're trying to solve**
Right now our team is using Azure DevOps Release Pipeline to build and push container images into ACR and we are using their [docker task](https://docs.microsoft.com/en-us/azure/devops/pipelines/ecosystems/containers/acr-template?view=azure-devops). I notice that ACR offers ACR tasks that can also automate the images' builds and maintenance, which comes with nice benefits such as [triggered updates on updated base image](https://docs.microsoft.com/en-us/azure/container-registry/container-registry-tasks-base-images). We would love to have this capability for our application image so that we do not need to keep track of the dependency base images, but I am not sure if the docker task in the Azure Release Pipeline could have the same effect as the ARC tasks.

**Describe the solution you'd like**
Is there any way we could leverage the the ability to automatically build images for us when a container's base image is updated, in the release pipeline task? Creating brand new ACR task may not be a good option for us because the context we use to build our image includes things outside of our source control (e.g. output from our build pipeline, external packages...)
