Login / Updateprofile : possible to define "success" URL, hash, or param?

I use Login, Updateprofile snippet in several forms placed inside tabs.

When update is successful Updateprofile reload the current page.

I would like to reload the current page adding hash parameter corresponding to the current tab (i.e. default reload page + #tab1)

(modx 2.3 + Login 1.8.1)
