There are 22 victory flags, no less, no more, no editing...
As I told you, if you want less, just pile them over on the same hex. Make sure all those on the same hex belong to the same country, for purely logical reasons. If the ones you pile over have a null value, the end result will be the same as if they weren't there in the first place.
In the "edit victory objectives" (scenario screen, hit deploy then press 'Z'), first click where you want the first flag to be, edit its parameters (country, value), then hit 'N', screen centers on flag #2, click where you want to put it, start over again while following the flag number in the top red bar.

Also, given the nature of your scenario, may I give you a bit of advice to prevent the Pasdarans from running all around the place. If you're ready to rebuild your scenario, save your map someplace, create a new scenario (version 2 of the current), and before buying and deploying any unit, change the engagement rules to "player 1 assault" or something. Then buy and deploy your Pasdarans first and entrench them all, they will be harder to spot and hit.
