How could I change volume keys on Xperia5 to the in-call or ring by default ?

Please How could I change default asociation for hardware volume keys UP and Down to the in-call or ringing volume ?

After pressing volume key UP or Down it change only Media volume. It  will be more usable for me if this volume keys can working by default for Ringing Volume, and if It is opened some audio application like Yotube or something than this volume keys can working for Media Volume - like for example on older models like Xperia ZX3.

Thanks
