MAAS Bonded vlan interface

I can easily see the ability to set up a bond and a vlan. im running into an issue where im noticing when i make a bond, it’s not able to gain connectivity through the vlan. i am familiar doing it in centos and it requires 4 files. 2 slave files 1 bond master and 1 bond.vlantag and i just dont see how to create that last bonded vlan interface on maas in the web gui. im using the latest downloadable version
any assistance is greatly appreciated
