Hi @abbigliamentodalavoro !
I would be more than happy to assist you today.
This would be possible only if they were “post”.
I mean, when you access the list of tables, if in the URL it says “?post_type=x”, this means that it is a post and the type of that post is the one that says X.
Then only in the case that the tables are post it would be possible to do it using our other plugin, AutomatorWP.
AutomatorWP allows to create automations, previously a series of triggers and actions are defined, in the moment in which they are fulfilled then it is executed, for example in your case the automation would be like this:
Trigger
– Create a user
Action
– Create a post
In this link you will find more information about AutomatorWP and an explanatory video. https://automatorwp.com/docs/getting-started/what-is-automatorwp/
Anyway if you have any questions, please let me know.
Hope it helps!
