OpenFlow Spec 1.3.5 says: --- 6.4 Flow Table Modification Messages ... For modify requests (OFPFC_MODIFY or OFPFC_MODIFY_STRICT), if a matching entry exists in the table, the instructions field of this entry is replaced with the value from the request, whereas its cookie, idle_timeout, hard_timeout, flags, counters and duration fields are left unchanged. ... --- So, FlowMod messages will replace the entire actions(instructions) in the matching entry with the value from the request. If you want to "append" new actions into the existing entry, just an idea, How about getting the existing entry by FlowStats messages first, then creating FlowMod messages using the actions from FlowStats reply body.
