for eg: 
rulesfile: [*rulesid_02,*rulesid_01]
target_list: [*runid_01,* runid_04]

##</code><code>##

where rulesfile pointing to respective fields is 

rules_file: 
- rules_file_id: &rulesid_02
   name: tpsm_rulesfile_BE        
   hostname: 

- rules_file_id: &rulesid_03
   name: test3        
   hostname: 

- rules_file_id: &rulesid_04
   name: test4        
   hostname: 

and target_list referes to :

run_target_platforms: 

- run_target_id: &runid_01
   target_controls:
     run_target_type: simulator    #simulator, emulator , hardware
     run_target_active: yes
   target_connection_info: 
     run_target_hostname: 

- run_target_id: &runid_02
   target_controls:
     run_target_type: hardware    #simulator, emulator , hardware
     run_target_active: yes
