you can aggregate the fields using a resident LOAD with a group by clause:
Concat([Cross sell lending products]) as AggrLendingProducts,
Max([CA Flag]) as MaxCAFlag,
Only([SBA Flag]) as OnlySBAFLag,
Sum([TD Flag]) as SumTDFlag
GROUP BY ID;
The aggregation functions Concat,Max,Only, Sum are just examples, since I don't know how you want to aggregate the field values. Chose a script aggregation function appropriate for your requirements.
