Wis. Stat. § 702.303: Intent to exercise: after-acquired power.

Unless the terms of the instrument exercising a power of appointment manifest a contrary intent, all of the following apply:

(1) Except as otherwise provided in sub. (2), a blanket-exercise clause extends to a power of appointment acquired by the powerholder after executing the instrument containing the clause.

(2) If the powerholder is also the donor of the power of appointment, a blanket-exercise clause does not extend to the power of appointment unless there is not a gift-in-default clause or the gift-in-default clause is ineffective.
