You can try entering the SQL query below: Tools -> Developer tools -> SQL. Copy and paste the results into Excel. You can filter out your impact categories, etc. from there.
Select tbl_impact_categories.name as category_name, tbl_impact_methods.name as method_name, tbl_impact_factors.*, tbl_flows.name as flow_name, tbl_categories.name as sub_cat_name, tbl_categories.name as cat_name
inner join tbl_impact_factors on tbl_impact_categories.id = tbl_impact_factors.f_impact_category
inner join tbl_impact_methods on tbl_impact_categories.f_impact_method = tbl_impact_methods.id
inner join tbl_flows on tbl_impact_factors.f_flow = tbl_flows.id
inner join tbl_categories on tbl_flows.f_category = tbl_categories.id or tbl_categories.f_category = tbl_categories.id;
