Gmaptool shows that v2016.10 SID subfile in gmapprom.img as CN_RUSSI.?

I15CF11C NT 24679343 1 1251 28 L 1 3755 PETROZAVODSK
MAPSOURC MPS 13378 1
I0000EAB TYP 14598700 1 1251 1 3755
CNRUSSIA TRF 2329195 1 1251

CNRUSSIA SRT 932 1
00003755 MD2 581052 1
CN_RUSSI ? 639985 1

But when I split gmapprom.img I can't find it. Is it possible that Gmaptool renames it like it does with NT files, e.g., I15CF110 -> 22868240.img?
