[Question] How to selectively publish APIs across diff instance of APIM env

### Release version

v6.0.1.10

### Question Details

**Background**
I have 3 different instances of APIM, 1 APIM instance for each env. E.g. dev, uat and production (PRD).
Each env have their own branch in Github too.

APIM between each env may not be the same, because APIs are in different stages of SDLC. More details below.

In Dev APIM will contains APIs that are Proof-of-concept, under development or for demo. When the APIs are ready from development or successful POC, i will put the APIs in UAT APIM for user testing. Once UAT is ready and user sign-off, only then the API will go into PRD APIM.

**Publishing Across Env**
My ideal flow of ApiOps (CICD + GitOps) is for main to be single source of truth.
So from main, i will generate the dev branch, then uat branch.
Any new API will be a feature branch from dev.

Flow: feature -> dev -> uat -> prd

**Issue**
There is currently no option to selectively publish specific APIs during promotion between environments.

The publisher supports only:

Full repository deployment, or
Deployment by specific commit ID

As a result, APIs that are not yet ready for promotion (e.g. unfinished POCs or APIs without user sign-off) get deployed unintentionally.

Hence will like to check if anyone has similar set-up and how you configure your CI/CD?

### Expected behavior

When Merge to higher env, e.g. from dev to uat
Able to select which APIs that are not to be publish e.g. in Publisher Config file
Only APIs that are not in it will be publish

### Actual behavior

Either publish by commit id or whole repo

### Reproduction Steps

- Setup 3 different Azure API Management (APIM) instances — one for each environment:
apim-dev (development)
apim-uat (user acceptance testing)
apim-prd (production)

- Configure the APIOps extractor and publisher pipelines, each linked to a different GitHub branch:
dev branch → apim-dev
uat branch → apim-uat
prd branch → apim-prd

- In apim-dev, create several APIs for testing or proof-of-concept (POC).
Example:
orders-api (ready for UAT)
inventory-api (still under development)

- Run the extractor pipeline for apim-dev, pushing configurations to the dev branch.
- Merge the dev branch into the uat branch to promote APIs to UAT.
- Run the APIOps publisher pipeline for the uat environment.
- Observe that the publisher pipeline publishes all APIs from the dev branch (both orders-api and inventory-api) to apim-uat.
