Need help for transforming mangle from nth to PCC matcher

This is mangle rules:

/ip firewall mangle
add action=mark-connection chain=prerouting comment="proba za moj komp" \
    connection-state=new disabled=yes in-interface=lan new-connection-mark="1_conn" \
    nth=3,1 passthrough=yes src-address=192.168.111.3
add action=mark-routing chain=prerouting comment="proba za moj komp" connection-mark=\
    "" disabled=yes new-routing-mark=1 passthrough=no
add action=mark-connection chain=prerouting comment="proba za moj komp" \
    connection-state=new disabled=yes in-interface=lan new-connection-mark="3_conn" \
    nth=3,2 passthrough=yes src-address=192.168.111.3
add action=mark-routing chain=prerouting comment="proba za moj komp" connection-mark=\
    "3_conn" disabled=yes new-routing-mark=3 passthrough=no
add action=mark-connection chain=prerouting comment="proba za moj komp" \
    connection-state=new disabled=yes in-interface=lan new-connection-mark="2_conn" \
    nth=3,3 passthrough=yes src-address=192.168.111.3
add action=mark-routing chain=prerouting comment="proba za moj komp" connection-mark=\
    "2_conn" disabled=yes new-routing-mark=2 passthrough=no src-address=\
    192.168.111.2

I tried to transform this into PCC mathcer without success.

Can anybody help me?

Remove the “connection state=new” setting
