OpenRA - Skirmish Game settings - Where are they stored?

[Ronald]

Hello All,
Is it possible to manually alter (e.g. before starting OpenRA) the setting in the menu below [Skirmish-Mode],[Player -options]?

If Yes:
- What is the name of the "skirmish player settings" file?
- Where can I find this file on my hard-disk (win7, 64 bits)?
