For those who do not write their own missions using the FMB....the best option is to download the excellent utility 'Quick Mission Tuner'
http://mysite.verizon.net/resvd35w/qmt/download.htm

this can quickly and easily open a mission and change aircraft/loadouts/skill/skins/regiments/weather
etc.

and can clone existing flights or remove flights or change the number of planes

best used with downloaded single/co-op/campaigns
