Timing issue for assigning periods to auto-loaded files

Summary:

We are setting a cash reconciliation flow in ARCS. Daily, a lot of files are loaded trough OIC into EPM. The issue is because the files often contain data of previous day, at month switch we get an issue.

Example:
At the 1th May, we load data of the 30th of April. The file is processed on the 1st so the date on the file is 01052025. But actually it should be put in period April.

Is there a way to let EPM read the file (accounting date) and assign it the the correct month to load? Or is there a solution in data exchange that can handle this problem? Thanks!
