More Sisterly Bonds to the same Sister

More Sisterly Bonds to the same Sister

There is something I still have to figure out: can one player give more than one Sisterly Bond to the same Sister?

This is something I am asking myself because it seems to me that, in a 4-player game (3 Sisters plus the Groundkeeper), the Sisters are left with just a little choice: they could only choose which of the other Sisters will get the first bond, and the other one will surely get the second one.
