I also do some refactor in this PR: #8151.
If it's a urgent request, we can merge this PR first and discuss more details later otherwise we can leave it here and after discussion let's combine these two prs. Thanks.

@KumoLiu when would be the timeline for the next MONAI minor release? It would be great if we can include this MR in the next PyPI distribution. Thanks
