[HELP REQUEST] EUP "Category" CHANGE

Hi, I need help, I want to change the category from Parachute (Hand) to Necklage (Teef), I was thinking to change the names from :

mp_m_freemode_01_mp_m_bikerdlc_01^hand_diff_004_a_uni.ytd
mp_m_freemode_01_mp_m_bikerdlc_01^hand_004_u.ydd

to

mp_m_freemode_01_mp_m_bikerdlc_01^teef_diff_004_a_uni.ytd
mp_m_freemode_01_mp_m_bikerdlc_01^teef_004_u.ydd

but It doesn’t work after many tries.

I hope anyone can help me, because I didn’t find anything on internet regarding nomenclature of the EUP files.

Did you find any way to change it ?
