Retry interval on failed shard allocation attempts

I couldn't find any information about it, is there (or will there be) an option to set the interval between each shard allocation retry attempt?

I am asking because even though I raised the retry limit to 20 or 30 on some of my indices, I am still reaching this limit occasionally and thus remain with unassigned shards until I manually handle it.

An interval of ±5minutes would have worked for my scenario.
What is the current interval?

Thanks

There is no delay, Elasticsearch will retry assigning unassigned shards as soon as possible.
