SRB missing text FUNTIONS

Maybe a stupid  question or  i looked just over it

: but why is a very usefull text Function  as CONCAT or CONCATENATE not 
available in the Sun Report Builder ?

I know, there are Queries to do things like that (supposes we build for 
every Report a new Query...), but Concatenate a part of  field with some 
'text' or other parts  is more handy than some other available text 
Functions.as URLENCODE etc...

Joining  the field parts  as separate  controls  is al so a work around  
but  by making  URL's  for   pictures  we need to do something like

concat('///myserver/mydirectory ; LEFT(TEXT[urlFIELD]);10); 'etc...')

Hope it helps to improve SRB and thanks for all the exellent work done 
to make this tool available!
