Recon for 'Import and Calculate Daily Rates import' ESS job

We have a requirement to import the daily rates more than once a day as we will be getting multiple files from source system(two files at same time), and we are importing the Fx rates data through FBDI.
For 'Import and Calculate Daily Rates import' job, we see that GL_DAILY_RATES_INTERFACE table is getting purged after the import is completed.
So for the reconciliation purpose we are using the import job start and end timestamp to identify the imported records in the GL_DAILY_RATES table since there is no other identifier to get the details of the records processed by the specific ESS import job.
