create an east soldier in the editor. Call it "Angel" or something like that to remind you that this is the solider that will be Angelina later.
Save!
Alt-Tab out to desktop, open up the mission.sqm from your users/username/missios folder.
Find the couple of lines that depict your soldier called Angel.
E.g:
   azimut=351.705994;
               id=74.000000;
               side="EAST";
               vehicle="SoldierE";
               leader=1.000000;
               skill=0.200000;
               text="angel";
See the line beginning with Vehicle = "soldierE"?
Change the quote to "Angelina" and that will transform your soldier into Angelina!
Now it looks like this:
   azimut=351.705994;
               id=74.000000;
               side="EAST";
               vehicle="Angelina";
               leader=1.000000;
               skill=0.200000;
               text="angel";
Save in Notepad and close it up, maximize flashpoitn and then load your missiona gan within the editor.
Preve and ta-da! There's Angelina
