Medal of honor allied assault expansions

Hi all,

I have recently finished Medal of honor Allied Assault SP campaign and want to now turn my focus to the expansions. I cannot seem to get them working by changing the Lutris Game options > Executable field. I tried changing it to any of the expansion .exe files instead. moh_breakthrough.exe and moh_spearhead.exe for example.
Has anyone managed to them working via the Lutris?
FYI I have installed the Lutris script via the MOH Warchest which was installed from GOG.
