Restrict Natural Account value by Journal Category when entering manual journals

Summary:

How can we restrict Natural Account segment values by Journal Category when entering manual journals?

Content (required):

Our client needs to restrict natural account segment values by the journal category name when creating manual journals e.g. for journal category 'Purchase Invoices' and source 'Manual', the natural account segment should display only the expense and liability types of accounts and not any other. Similarly for 'Sales Invoice' , it should show only the revenue and asset account types.

We have segment security rules feature in GL, however, that doesn't seem to work there because that works at the role level and not the journal category.
