May a woman make a Hefsek in middle of Pesukei Dezimra or does it have the same law as a man?

A woman who recites Pesukei Dezimra with the blessings of Baruch Sheamar and Yishtabach, may not talk or motion during Pesukei Dezimra just as we rule regarding a man.

The reason: Although women are exempt from Pesukei Dezimra according to Admur and other Poskim, nonetheless, if they choose to say it, they may not make an interval in between just as they may not make an interval the blessing over Lulav and the shaking of the lulav even though they are exempt  from the mitzvah.
