Run subset of specs from file

[SebastianSolidwork]

I'd like to select which describe or it should be executed from a file. Especial during the development of concrete test case i just want to execute that single one, not all others included in the test.
Therefore should the file analysed and a visual hierarchy presented. Maybe from the context menu.

describe('1', ()=> {
  describe('1.1', ()=> {
    it('1.1.1', ()=> {
    })
    it('1.1.2', ()=> {
    })
  })
  describe('1.2', ()=> {
    it('1.2.1', ()=> {
    })
    describe('1.2.1', ()=> {
    })
  })
})
describe('2', ()=> {
    it('2.1', ()=> {
    })
    it('2.1', ()=> {
    })
  })
})

Should result in:

• 1
• • 1.1
• • • 1.1.1
• • • 1.1.2
• • 1.2
• • • 1.2.1
• • • 1.2.2
• 2
• • 2.1
• • 2.2

Every level should be selectable .
Is this possible here? Or does it depends to much on jamsine?
