Short answer, no.
Long answer - think about what the compiler would have to
do to implement this. Do you really want this "under the hood"?
So you basically need to do it yourself, a couple of macros will
help, e.g.

bank1 char      buf1[0x40];
bank2 char      buf2[0x40];

#define array(x)        (((x) >= 0x40 ? buf2:buf1)[(x)&0x3F])

IOW, use the high bits to select an array, low bits to index it.
Can be extended to bigger sizes.
