Akka Persistence - DynamoDb - TTL/timestamp

Hi, we would like to add an attribute to enable dynamodb TTL so we can utilise this feature:

https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/TTL.html?icmpid=docs_dynamodb_help_panel_hp_ttl

https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/time-to-live-ttl-before-you-start.html#time-to-live-ttl-before-you-start-formatting

is it possible to add this attribute while using akka persistence/dynamodb plugin?

thanks
