Not sure I understand correctly what you mean.

We can make alias now, using equate.  This is what I usually do for gps fixes.

In a cave survey 'index data file'...
centreline
cs lat long
fix gpsEntrance01 <lat> <long> <altitude> [<stderr> etc ]
fix gpsEntrance02 <lat> <long> <altitude>
etc

equate gpsEntrance01  53@<survey1>
equate gpsEntrance02  1@<survey14>
equate gpsEntrance01  AliasNameCreatedByThisStatement
endcentreline

ie 53@<survey1>, gpsEntrance01 and AliasNameCreatedByThisStatement are all 
alias' of each other.  They all refer to the same physical point. The last name 
is created by the equate statement, whereas the others all exist prior to the 
execution of the equate statements.

Or were you meaning something different?
