How to detail an internet expense record in two records in order to split the VAT amount in two?

Our accounting department requires to apply some changes in the Internet Expenses entered by users.

The detail available regarding the VAT is not precise enough.

For example, an employee has been to a restaurant. He enters an internet expense in OIE for the global amount 105,70€ (cf. attached screenshot). Part of it regards wine (30€), and the other part is food (75,70€). Both have different tax rates and our accounting team needs to book the details.

Therefore, they ask for adding a new record in the expense, in order to split the food and the wine.

We already know that one solution would be to update our expense's models, but we don't want to ask the employees to enter such details. It would be too much for them...
