halacha - Have women accepted Zachor on themselves?

Women are exempt from hearing shofar, but some hold they've accepted it upon themselves and are, for that reason, now required to hear it.

There is a dispute whether women are required to read/hear parashas Zachor, but the common practice nowadays is that they do so. I wonder whether anyone has argued that they have accepted it upon themselves and are for that reason now required to do so. Any authoritative source to that effect would be valuable, as would any authoritative source that specifically debunks the notion.
