Would anyone happen to know if there is a way to separate Journal Entry Forms between Statistical Journal Entries and Standard Journal Entries, both share the same form much like Customer, Prospect, Lead forms

you might be able to set the custom form via workflow or scripting, since statistical JE is only available when you have dynamic allocation turned on - which can be the key for distinguishing the JE type then setting the form accordingly

NetSuite typically keeps automated JE as bookspecific. Can you check that of it is marked. You can use that as an identifier. Also, you can put a batch job to custom checkbox this N JE if you need to pull in reports.
