VAT in Retainer Invoice -UAE

VAT in Retainer Invoice -UAE

It's currently not possible to add VAT to Retainer Invoices. UAE TAX LAW however makes VAT mandatory on each retainer invoice in UAE  So basically, what i'm saying is that if you don't allow us to add VAT to Retainer Invoices, than the whole Retainer Invoices becomes totally useless 

Can you please provide some update on this ? Has this been approved or withheld for the development pipeline?  And if so, when could the feature go live?   Again, it's just to allow for addition of VAT to Retainer Invoices so i can't imagine that would be a long or difficult thing to do.

Your feedback would be much appreciated.
