Money soft and Peoples Pension problem

I currently use Moneysoft for payroll and Peoples Pension for auto enrollment for one of my clients.

The client has 5  employees and now one them wants to move to a salary sacrafice scheme.

Moneysoft say i would need to set up a sepreate scheme for the peoples pension which calculates the pension on a salary sacracfice basis for the one employee. This would require two submissions per month for the client, one for the employees on the standard scheme and one for the the employee on the salary sacrafice scheme.

Peoples pension say that they can only except one submission per month therefore this method will not work.

It has been sugested that i create a new worker group in moneysoft and manually enter the salary sacrafice amount in the employers contribution cell and upload that. this would show all the contribution as a employer contribution. This would remove the need to create a secound file / scheme.

If i did this would this arrangement be acceptable under salary sacrafice rules ?

Also the employers contribution.Would this be calculated on the salary amount before or after the salary sacrafice. I have been told by Peoples Pension its on the amount before the sacrafice ? But surely his salary has now been reduced so i would have thought it would be on the post sacrafice amount.

Thanks for all replies
