Use Siri Shortcuts to enter specific amount and category

The integration of shortcuts is great, however it is not much use to me because only being able to add the same amount to the same category is not very helpful.
I don’t know if there is a technical reason why this has not been implemented but I would love to know.

(E.g.: “Add to MoneyCoach [Amount] to [Category] for [Name] payed with [Account].”)

Thank you :)
