Email subscriptions for multi-tab reports

I'm able to see that by subscribing to a Power BI report, I can set it up to email me on a schedule.  I'm running into difficulties with a report that has multiple tabs, whose data depends on a customer that is selected from a drop-down in the first tab.  When trying to set up the subscription, the only option I seem to have in the "Report page" drop down is the very first tab (the one that contains nothing but a customer drop down). 

1) How can I select the other tabs as well?

2) How do I go about filtering the data that will get emailed from those tabs?

3) If I have a tab that contains sales order information for several sales reps, can I set up a subscription that can filter the data down per rep and send it to those rep emails dynamically based on the data set (as opposed to using an Active Directory group or individual email)?

I appreciate the help!
