nop, the game only used 1350 pictures for ps4, i ve have a solution
for example in one user i rename all kits of bundesliga (liga PEU) to PEU01 p1.png, PEU02 p1.png the same with emblems, then i can import over second log diferents teams but kits and emblems renamed like that, the game overwrite and dont use more slots
for ej ps4 user1
have in peu1 (pes united) Bayer Munchen like this
PEU01 p1.png
PEU01 p2.png
PEU01 g1.png
PEU01 (this is emblem)
and in user2 ps4 have Rangers
the same named kits and emblems but diferentes players and only need to import pictures (hte game rewrite that images for new ones)
i hope you understand
