yes, that is possible.
You should look up these topics in manual:
mangle, routing-mark
http://wiki.mikrotik.com/wiki/Manual:IP/Route
http://wiki.mikrotik.com/wiki/Manual:IP/Firewall/Mangle
where you can set up routes as you require and in mangle set up routing mark, so that traffic is sent through gateways you require.
