Get messages by timeRegistration

Hi.
We migrated to Wialon from another service that allowed us to work with messages directly.
We can also receive messages here, but I haven't discovered a way to get only updates.
We attempted to obtain messages in the following ways: 
1. Retranslation - is risky as there is no guarantee of data integrity control. Wialon doesn't verify whether or not I have received a message, so I cannot determine if I missed a message and request it again.
2.notifications - we've put message data into notification as pseudo JSON and parsed on our side - disadvantages are the same with the retranslator + data lost when there is more than 1 day lag.
3.Events report - we register notifications as events and load for all wehicles at a once - This prevents data loss on transport level, but not for data lagging. it is also wery  resource intensive.
4.messages/load_interval - the most reliable way of getting messages but also the most resource intensive as the previous one.
5. messages/load_last - most useless in this case.

All of these methods do not provide the ability to get messages by registration time.
If some of the objects was out of cellular network and sent data with a significant delay - i cannot get that data easily. i need to load all messages since yesterday for example, and then using method 3 i can get their registration time and add to my table.

Is there some way I've missed and if not - could you provide a more convinient method for getting new messages by filtering by registration time (time when Wialon received the message)?

Thanks
