For a Manual Harness Approval stage, I want to dynamically create "allowed values" for an approver Input. Currently, you can dynamically select the default value (with expression syntax) of the approver input, but you cannot dynamically set which allowed values that input has, and which values will be selected by default if it is a multi-selection. This would be an extremely helpful feature for my Dataform implementation.

The value for the multi-selection block should be a single string, with separate items separated with a "," and have expression functionality
