Can i use the external SD card as internal storage on lollipop?

Hey guy,

can i use the external sd card as internal storage on android 5.0.1? My girlfriends samsung galaxy s4 value edition (I9515) has a very small internal storage but she cant do any app on the 64 GB external sd card. So i want to simulate the external sd card as internal storage. Is this possible on lollipop`?

Greetings,
