How to predefine no.of entites in a entity_bat​ch_creator​_block in simevents

I want entity_batch_creator block to take no. of entities from its previous block without explicitly defining it in the dialog box.

That is if for a specific time period no of entities generated are 20 then the entity batch creator takes the batch of 20 entities automatically.
