Grails gsp intellisense for g:set

I would like to suggest support for this.

If i have a .gsp page in my Grails application theres no support intellisense wise for this neither in refactoring, go to declaration aso.

in a .gsp page:
<g:set var="myService" bean="myService"/>
${myService.myMethod()}

in MyService.groovy
class MyService {
String myMethod() {}
}

if you refactor myMethod() the code in the .gsp file is not included.
Like wise if you select myMethod() in the .gsp file and select go to implementation nothing is found

Reproduce the example in a .gsp page using and MyService.groovy with myMethod(). Start by checking how refactoring and Go to Declaration/Implementation behave for myMethod in the .gsp file; done means these actions include the GSP reference and resolve it to MyService.groovy.
