Applying extra damage to weapons already enchanted.

[gimchi]

Is it possible to apply spells like flame weapon, or feats like anointed weapon, to weapons that already carry elemental damage?

For example can AK electrical damage be applied to a weapon with existing fire damage? What about the AK massive critical property, can that be added?

TY for replies

Two different elements work. Electric + fire works, for instance. Fire + fire does not, it chooses the highest.
