You cannot do it with the structural CDX (those open implicitly)
because, as for the file memo the name is implicit: tablename.cdx

But, you can do it with a not structural cdx:

use table1.123 alias table1_123
INDEX ON somekey TAG someTag OF table1.123x
INDEX ON somekey2 TAG someTag2 OF table1.123x
...
USE
*
* OPEN
use table1.123 alias table1_123 INDEX table1.123x
