Move Part Attributes Tab

We are adding a couple more tabs of attributes (UD fields) to Part Maintenance. I would like to move the existing Attributes tab to dock under my new tab so it’s on the same level as the new set of tabs. However, The existing Attributes tab doesn’t seem to want to dock to anything other than the highest level tabs. I tried using code to change the Parent of the Attributes tab to new tab but that doesn’t work. I’m thinking there are more properties that need to change. Can anyone share some code that nests a tab under another one.

E10.1.400.38

Thanks,
