Is it possible to load custom grok patterns at the startup of logstash ?

i would like to avoid loading grok filters each time

> filter {  
> grok {  
> patterns\_dir =\> "/etc/logstash/grok/"  
> match =\> { "message" =\> "%{CALL}" }  
> add\_field =\> { "[@metadata][pattern]" =\> "parsed" }  
> tag\_on\_failure =\> [call\_parse\_error]  
> }  
> if "call-in" in [message] {  
> csv { separator =\> "|"  
> columns =\> ["timestamp","id","call\_type","plan\_id","bill\_id","caller","callee"]  
> add\_field =\> { "[@metadata][csv]" =\> "matched" } }  
> }  
> else if "call-out" in [message] {  
> csv { separator =\> "|"  
> columns =\> ["timestamp","id","call\_type","plan\_id","bill\_id","caller","callee"]  
> add\_field =\> { "[@metadata][csv]" =\> "matched" } }  
> }

No; there is no way to set a global configuration that affects all instances of a plugin.
