Breadcrumbs in highchart-treemap

问题:

I wanted to know if its possible to design breadcrubms in highchart treemap. For now, there is only a back button which helps in getting back to the first level from 2nd drill down. I am expecting something like this for example : if first level has tiles like animals, vegetables, fruits. second level would be animal names, vegetable names etc. so when i click on animal tile, it will display all the animal names and the breadcrumb should look like : project>>animals and if i select vegetables, it should display something like this project>>vegetables and i should be able to navigate to the previous level using these breadcrumbs, instead of the traditional back button which is got on the right side of the treemap. I wanted to know if that kind of feature is supported by highcharts!
