The setting for WB is set until you change it.
Don't forget that WB is situational, meaning: the WB you set for that shot under that lighting (in broad terms) may not be correct for the next location. even if you change rooms in your house, the reflective ambient lighting from furniture/walls and the amount of natural light (coming at the particular time of the day) changes.
I general I shoot in AWB because I shoot RAW and can correct it in Lightroom and DXO, the consistence of the lighting changes (inside/outside) throughout a single shoot.
If I am shooting in the same lighting for the whole day or shoot, then I will us one of the pre-sets or grey card it.
