We have the same case in Poland. We did not include this into our Starter Pack app but we need to consider this functionality to our next version. It will be very helpful to have it in W1. PLease find below short introduction to this functionality:
General Information
In some cases, it is not possible to deduct the full 100% purchase VAT amount, which means that only a part of the VAT amount can be included in the VAT register and the remaining part should be added to the purchase amount and posted as costs. For item or fixed asset purchases, non-deductible part of the VAT amount is added to the purchase value of an item or fixed asset and it is posted as a part of the purchase cost.
Polish Functionality for Microsoft Dynamics® NAV 2018 has been enhanced with this feature to enable users to:
• Set up the partial deduction of a calculated VAT amount;
• Post a purchase transaction including the calculated VAT amount which is partially deductible;
• Increase the acquisition cost of items and fixed assets by purchase VAT which was not deducted.

In case of any questions please let me know.
Regards
Wojciech
