Fetching the expenditure batch submitter and approver details in workflow tables

We want to add Approved by , Approved date, Submitted by , Submission dates in our BIP report to fetch Project Expenditure Batches data for earlier months i.e., Jan, Feb, march etc... from FA_FUSION_SOAINFRA.WFTASK table

However the workflow tables are storing only 30-60 days of data. Do we have any workaround or alternate source to achieve this goal.

Below is the reference screenshot to fetch those approver details from Manage Expenditure batch page in oracle fusion.
