NAT with multiple IP's

Is there a way to masqurade an IP range to ‘multiple’ public IP’s, with a round robin like behavior?

Example:
local network on LAN interface
10.0.0.0/21

External IP’s assigned on WAN interface
10.1.0.1
10.1.0.2

How does the mikrotik decide what IP to masq to? does it use both?

Thanks,

for extended capabilities, use ‘src-nat’ instead of ‘masquerade’:

action=src-nat to-addresses=10.1.0.1-10.1.0.2

Worked very well. Thanks!
