Can I change the function key defaults?

[bgsather]

I recently purchased a Logitech Ultrathin Folio S410 for my Galaxy Tab 4 and loving it so far except for one detail.

Is it possible to change the default apps that are opened with the function keys?

For example, Function-5 opens Google Music but I want it to open Amazon Prime Music. Is this possible to change?

Any suggestions would be helpful. Thanks.
