@samuel I basically did a work around - see example workflow here:
I basically created a list of numbers for a repeating group to reference. So when a client filters these group through inputs, I can then create a copy of the filtered list via an API call to another to list. Basically I wanted the button to create X number of records in a click that is associated with a particular type.
I am then planning to amend those records via Make changes to a list of things, to add ID, which will allow me to add the list of inputs.
@emmanuel a create list feature is so much needed, if to avoid abuse, limit to 50. Otherwise, I am using custom states, which I yet to figure out, how to add to these records after say 12-15 seconds. Meaning that if the API call is slow, then certain records do not get an ID.
