Toolbar button: session targets

I know you could end up adding a toolbar button for nearly everything (and that would be wrong), but I would love to be able to click on a button at the start of every session in order to reset my target count for that day!

Perhaps I am missing something, but I think the only place you can even see the session counter is in the Project Targets window which already has a reset button.

No, I meant I would like to customize my toolbar by adding a “Session Targets” button – one stop shopping, as it were, when I start a writing session. (Rather than going to View > Statistics > Targets.) Not crucial, just less work.

I didn’t see any way of adding custom buttons to the toolbar, and I didn’t see a targets button in the “Customize Toolbar” window.
