Is there a git-native way to fast-forward merge multiple branches?

Question

I'm working on an infrastructure-as-code deployment, managed with git and some build piplines.

We have a branching structure like below. We develop on master, move test forward to a specific commit/branch, and eventually move forward the prod-company-X deployments to a specific commit/branch. Below is obviously simplified, we have many production deployments.

* 1fee83a - (1 day ago) Implement New Feature E - Caesar Kabalan (master)
* 629a6c6 - (3 days ago) Implement New Feature D - Caesar Kabalan
* a5596f0 - (5 days ago) Implement New Feature C - Caesar Kabalan (HEAD -> test)
* de59ad0 - (10 days ago) Implement New Feature B - Caesar Kabalan
* 1aa293b - (20 days ago) Implement New Feature A - Caesar Kabalan (prod-company-a, prod-company-b, prod-company-c, prod-company-d)
* bd1654f - (1 month ago) Initial Product Release - Caesar Kabalan

In our example we would like to move all prod-* branches to the test level, resulting in:

* 1fee83a - (1 day ago) Implement New Feature E - Caesar Kabalan (master)
* 629a6c6 - (3 days ago) Implement New Feature D - Caesar Kabalan
* a5596f0 - (5 days ago) Implement New Feature C - Caesar Kabalan (HEAD -> test, prod-company-a, prod-company-b, prod-company-c, prod-company-d)
* de59ad0 - (10 days ago) Implement New Feature B - Caesar Kabalan
* 1aa293b - (20 days ago) Implement New Feature A - Caesar Kabalan
* bd1654f - (1 month ago) Initial Product Release - Caesar Kabalan

Thus far we've been using a script which loops through branches, checking each out and merging it with our target branch.

Is there a git-native way to move all branches, or a subset of branches, to a specific commit or other branch? Something with merge --ff-only would be preferred, but we're open to reset --hard or less "safe" options.
