With one GARMIN GPSMAP 60CSX, Is it possible, have multiple file name of img

ex:
  1. topo 1.img
  2. gmapsupp.img
  3. trakmap marine.img


MY SD:\GARMIN\topo 1.img AND topo 2.img and gmapsupp.img and trakmap marine.img ect...
all in same directory "garmin" same oregon, montana or new gps series ?

it would be easy to make a test

But now I have not the hands to make a test, this is one of my friends.

Thanks and sorry for my bad english
