Hi Jeff,
there are several options, showing hiere for a Kinetis device.
First if you move the mouse over a pin it shows the pin name which includes the functions:

If you click on a peripheral it shows which pins can be used for that function:

In the table view you get all the possible assignments for a pin. For example pin 28 can be GPIO, FTM Timer, UART, ....:
That's what you see in ohter tools as 'grid array', not sure if you have missed that one?

If you click on the checkbox, you get a list of possible assignments:

I hope this helps,
Erich
