[SR-Users] ndb_redis value substitution or escaping spaces

I am aware of, and have used sucessfully, the %s substitution option in redis_cmd, however when trying to do 4 values I'm getting a parse error about too many arguments. A review of the module's source appears to indicate that there is a hard limit of 3 substitution values when using this method. Is there a suitable workaround anyone has for this to enable insertion of values with spaces in them that won't get interpreted by Kamailio itself? Escaping the value, even by using $_s to eval a dynamic string, ends up with Kamailio itself apparently trying to parse the escape and breaking things further. Thanks!
