In Forms, select lists available are only the ones "manually" created as "single column" or "multiple columns".
It would be great to allow select lists based on an index field in a File Cabinet. For Example : select list based on an index named "Customer" in a dedicated File cabinet, which could be updated/populated via other datas' assignments in a WF, after sending the Form.
This way the select list would be always up to date, with no need to add manually a new entry in the "fixed" select list or update any csv file or FTP file as well.
It would be great I think, isn'it ?
