A multiselect button for the relationship tab...

Can we have a multiselect button on the relationship tab? I've been playing with the GTW: Retail store a lot lately and my sims' relationship tab is bloated with sims. It would take me about 10 minutes to hide the relationships one at a time. Then I would have to do it again every time I close the store. 

With a multiselect button I could select all of the sims and banish them all at once.
