FeatureGroupSubGroup: nth level subgroups

Describe the bug
I am using quite a few levels of recursion to generate a map that has subgroups within subgroups, and im not sure how to fix the issue, or if there is a better method.

To Reproduce
theres alot going on here... the repeated for loops are to keep the buttons ordered by hierarchy.

df['Result'] = (~df['Impounded'].isna().astype(int)).apply(lambda x: _results[x])
df['Interval'] = (datetime.now() - df.index).days
