Gradient has an option to automatically determine the number of steps between the two colors. Users can override this option and set, for instance, a small number of steps. Adding the manual configuration as a new preset (as well as modified an existing) works for all properties except the automatic checkbox, which is always on.
In area dialog go to gradient.
Select black and white for the two colors
Uncheck 'automatic' and decrease the number to 8
Add this setting as a new preset
Switch to another preset
Loading the preset has automatic always enabled

This is a GSoC-friendly hack.
The code is in cui/source/tabpages/tpgradnt.cxx.
The meat is in ChangeGradientHdl_Impl function. Put a breakpoint into it and find out why is the checkbox (m_pCbIncrement) always set to checked/true.
