Final Accounts - Changing P&L Headings

We have recently moved from the desktop SAPA version to the online final accounts and I am very disappointed to find out that we cannot change any of the P&L headings to tailor to our clients needs.

The biggest one I am struggling with at the moment is that one client has Research and Development costs which have historically always been included within cost of sales.  However, Final Acccounts won't let me do this and so I have a set of accounts now with R&D in the administrative expenses which makes my client gross profit line look extremely odd and not comparable to previous years.

Does anyone have any suggestions please?
