Transaction Matching Data load replace instead of incremental data

Summary

Need to figure out how to replace data loaded into target match type instead of Incremental data load

Hey There, 
So we are trying to load some data into one of the match type sources. We want this particular location to have data replaced in each load. These are just unposted transactions which througout the month keep on getting posted and so are there for information only. 

However, even if i use the below epmautomate command, data gets added to the source match type incrementally. 

epmautomate runDataRule $RULE_NAME $period $period "REPLACE" "REPLACE_DATA"

I am wondering what combination of impoert_mode and export_mode do i need to try to make sure all data loaded into match type source gets replaced with every file load.
