Pension export to contain annual salary details as required by pension provider

The pension export for one of our pension providers is not recording the salary information correctly. Pension contributions are correctly being calculated on salary (inc multiple role) plus allowances. However, the annual salary figure shown on the csv file is the basic pay only, not including any allowances.

The pension provider have confirmed that the annual salary should include all pensionable pay but I am told that this cannot be amended in the system as no-one else has asked for it. To me, it seems that an export file (set up by staffology for a specific provider) should match the provider requirements but this is not the case, so I was advised by the help team to raise an idea to request that pension exports contain the details required by the pension provider.
