There are no special flags to show if a payment was settled early or not. 

Automatic early settlements are the same as normal settlements except that they are settled at T+0. So you can find the settlements in the settlement report and the combined report as done currently. To know if a particular payment or batch of payments were delayed and NOT settled early, you can check the settlement date on the settlement report. 

On-Demand Early settlements are payouts (direct settlements). Hence, such settlements will appear as payouts in the settlement report and the combined report. If you have to perform any recon, do it manually as payouts cannot be mapped to any incoming payments because they are made out of merchant balance.
