Customer 360: Add customized search options to bare C360 page

I discovered today while poking around the February release that if I go to the following link:  https://URLtoGainsight/apex/customersuccess360  it will take me to a screen that looks like this:

This is great actually, because people are always asking me how to get to the C360 page and I have to remind them it is via the Customer tab, searching for the customer and clicking on the customer name.

But even though I have configured advanced search options on the C360 page to include Account Number (and it works when I am on a populated C360 page) the advanced option does not seem to work from this screen.

It would be great if we could have that function work here as well, because this could be a shortcut for our CSMs who have the account number memorized to quickly pull up an account page.
