In order to merge two loan applications, you can export the loan file of one of the loans and then import in another loan.
For example; you have two loans, A and B. You want to merge Loan B with Loan A
To do this please go to Loan B > Click on the three horizontal dots in the top right corner > Click on Export FNM 3.2/Export MISMO 3.4 > Your file will be exported.
Now, please go to Loan A > Click on the three horizontal dots > Click on Import FNM 3.2/MISMO 3.4 > Select the downloaded FNM 3.2/MISMO 3.4 for the Loan B which you exported earlier and upload. Once the file is uploaded- the loans will be merged.
