CAN COUPLES ACCOUNTS PURCHASE ONCE FOR BOTH ACCESS?

OK WE GOT TWO XBOX 1S AND TWO ACCOUNTS BUT WE LIVE IN THE SAME DAM HOUSE AND WANNA PLAY THE SAME THINGS AND YET HER INFO PROFILE DIDNT TRANSFER WITH THE GAME {THIS DOUBLE BUY THING FOR COUPLES REALY SUCKS ..THERE SHOULD BE AT LEAST SOME CONSIDERATION IN
THIS ASPECT SO WE DONT HAVE TO BUY IT TWICE ...I MEAN OBVIOUS ONLY ONE OTHER PERSON AS A COUPLE WOULD BE EXPECTED BUT AS A JOINT ACCOUNT KINDA SETTING... SO WE CAN ACCESS AND SHARE OUR INFOS AND PURCHASES INSTEAD OF FEELING DOUBLE RIPT AND GYPT ON HAVEING
TO BUY THINGS TWICE,,,WE KNOW WE COULD PLAY ON ONE BOX BUT NOT TOGETHER AT THE SAME TIME [SPECIFICS OF THE GAME THAT REQUIRE SEPERATE BOX FOR THE SEPERATE TV]... WE GOT ALL THAT BUT GAMES WE PURCHASED AND PLAYED CURRENTLY CANT BE PLAYED BY HER ACCOUNT WHICH
REALY SUCKS MAJORLY WHEN IT SHOULD BE ALLOWED FOR SETTINGS AS A JOINT ACCOUNT JUST TO MAKE PURCHASES SEEM MORE PROPERLY AQUIRED FOR BOTH ITS NOT LIKE WE BUY 2 TOILETS AND 2 TUBS AND SEPERATE BEDS ...SO REALY THIS AINT HYGENIC DIFFERENCES TO REQUIRE DOUBLE
PURCHASE ESPECIALY FOR COUPLES ....SO IT NEEDS A FIX...AND IF YOU AGREE LET THEM KNOW AND ADD SOME LIKES OR LET THEM KNOW HOW YOU FEEL TOO BECAUSE THIS JUST AINT RIGHT...ADD JOINT ACCOUNT OPTIONS WITH THE LIMIT OF TWO PEOPLES ONLY SO PURCHASES CAN BE SHARED
AND PROFILES ACCEESSED ACCOURDINGLY AND RETURN THE PROFILES SAVES AS A MOVEABLE FILE THAT WE CAN SEE AND TRANSFER AS WELL ...I MEAN IT JUST MAKES MORE SENSE SO PLEASE HELP.... WE DONT LIKE BUYING TWICE JUST FOR ONE HOUSE OF TWO ACCOUNTS ESPECIALY WHEN IM THE
ONE THAT MAKES BOTH PURCHASES
