why not define your floods as 3 channels like this
1 flood1
7 flood2
13 flood3
then make a single string, 1 light dummy light starting on channels
4 dummy1
10 dummy2
16 dummy3
on the dummy lights set a colorwash of red where you set the rgb value to 189,0,0
Now in your sequence u can control the rgb floods
just leave colorwash on the dummy lights (put colorwash on in the first row and blanks all the way down , this will keep the colorwash keeping outputting 189 on the very next channel above the floods
