You can use the SUBST command to set up logical drives that equate to 
a subdirectory, then use the drive name in the path.
 
SUBST D: C:\level1\level2\level3
SUBST E: C:\layer1\layer2\layer3\layer4
PATH=D:\level4A;D:\level4B;E:\layer5

Remember to put a LASTDRIVE=d: in your CONFIG.SYS if you need a drive
after E:
