Way to generate indices which supports rollover with elasticsearch_dynamic fluentd plugin

I want to perform rollover for fluentd generated indices. Currently, I am using elasticsearch_dynamic plugin and generating dynamic indices with help of logstash_format and logstash_prefix parameters. However, with these indices rollover is not possible as fluentd pushes data to these indices and not through any alias.
Is there any way to give dynamic alias in fluentd configuration and push data to those and perform rollover for them. Please suggest.

Please look into this and update
