Is there a way to set the allowed values of a parameter in Azure DevOps using some kind of a variable? For example, let’s say we have this parameter in 100 different pipelines:

I want to be able store the values array below somewhere global:

parameters:   
 - name: value   
    type: string  
    values: [value1, value2, value3, value4, value5, value6, value7]

The only way that have worked so far is a script that over-writes all the parameters with a specific name. For example:

1. Scan all files for parameter with name “value”
2. If found, over-write it with the updated values array.
   However, this is far from ideal.

Here is what hasn’t worked:

Using Global Variables

variables:
  - group: variable-group

parameters:
  - name: value
    type: string
    values: [${{ variables.valueList }}]

Using Template

parameters:
    template: values.yml 

OR: 

extend: values.yml 

With values.yml:

parameters:   
 - name: value   
    type: string  
    values: [value1, value2, value3, value4, value5, value6, value7]

Anchors aren’t supported by ADO. Any other ideas?
