Need Support: Dynamic refer for Fn::Transform

[pek77]

Hi Team,
Is any possible support Fn::Transform name for dynamic refer?

I wanna use Macro(Fn::Transform) by using dynamic refer, such as Aws.StackName or Import Value.

When deploy, it says: Key Name of transform definition must be a string.

Because I deploy a new Macro for name AWS::StackName and wanna use this name for dynamic refer.

 "Fn::Transform": {
         "Name": {
          "Ref": "AWS::StackName"
         },
         "Parameters": {
          "InputString": {
           "Ref": "AWS::StackName"
          },
          "Operation": "Lower"
         }
        }
       },

Is any possible support this feature?
