For example, If a user sets up a constituent record set up with a button going to the Constituent Page, and the Default Tab is Revenue, but then also want it to specifically go to the Revenue History SubTab. This option is not available.

Please re-evaluate this as I suspect that the OP is asking for the page designer to have the ability to specify the sub-tab that the button goes to, not simply go to the first tab in the sub-tab collection.
This can be, and is often, different, as users can change the first tab, as covered by Nicola. Being able to specify the sub-tab within the configuration of the button or hyperlink would mean that the designer can ensure the user lands on the correct sub-tab immediately.
This is achievable by dragging and dropping the Sub Tab to the required position on the main tab while in Design mode.
