Well last but not least i think you also have to take look or learn how to use SEARCH button...well to change the uni XO * easy just find the ID of Uni XO you wanna change the start and then change the grade..
For Example you said you have got 36* Uni XO in box but its hatched as 32*Uni Xo right?
easy try use this query:
update cq_grade set rarity= 1500 where id= 1071980;
update cq_grade set rarity= 1500 where id= 1071981;
update cq_grade set rarity= 1500 where id= 1071982;
1500 is 15*
2000 is 20*
3600 is 36*
REMEMBER Every Universal XO got their Own ID so you need to replace with yours ID Of Universal XO then edit the start you want just like i showed to you just now..hopefully this help you
