Restrict posting to certain segments or GL account at group/user level

Hi, I was wondering if it is possible to restrict posting to accounts to certain users / security groups for example one user can only post to segment/cost centre 1234 so for example all GL accounts starting with something else they wouldn’t be able to post to? Either Journal posting or coding to invoice etc?

Epicor Finance module is designed to be as single source for a company, unlike other modules where you have user-wise rights based on sites. Therefore, it is not possible to give user-wise GL access in standard module, however, it is possible thru customization and customizing searches.
