dafault ping size

I noticed that whenever I use the ping command in mikrotik, the default packet is 56 bytes.

[admin@client2] > ping 192.168.1.27        
HOST                                     SIZE TTL TIME  STATUS                                    
192.168.1.27                               56  56 897ms
192.168.1.27                               56  56 337ms
192.168.1.27                               56  56 306ms

Is there a way to set the default packet size to 32 bytes only?
