在Zend1中的ini config中配置database.defaultMetedataCache的缓存前缀

I have configured in .ini file in Zend Framework 1 cache. It uses redis but i think it is not important. In the same ini file i have configuration forn saving in cache db_table metadata:

resources.db.defaultMetadataCache = rediscache

Problem is that I want to use different cache_id_prefix only for that data. I can copy all lines of cache configuration with different name but looking for better solution. Maybe there is an option for one-liner

resources.cachemanager.redisdbcache.parent = resources.cachemanager.rediscache
resources.cachemanager.redisdbcache.frontend.options.cache_id_prefix = dbcache_

Any ideas?
