SpringBoot Enhancement: Proxied @ConfigurableProperties that allow for dynamic resolution of placeholders (templating properties)

I think the framework could benefit a lot with something like the following:

my.application.templated-property="baseValueWith${myDynamicValue:}injected"

System.out.println(myApplicationProperties.getTemplatedProperty()); //Prints "baseValueWithInjected"
System.setProperties("myDynamicValue","MyProperty");
System.out.println(myApplicationProperties.getTemplatedProperty()); //Prints "baseValueWithMyPropertyInjected"
System.setProperties("myDynamicValue","MyProperty2");
System.out.println(myApplicationProperties.getTemplatedProperty()); //Prints "baseValueWithMyProperty2Injected"

Is this feasible or doable in an easy way by means of an existent framework trick?
