Have expense taxes be opaque to the client?

Is there a way for expenses with tax to be invoiced for the whole value (including tax), without showing the tax breakdown to the client?
eg if I buy something for 1$ taxed at 10%, then when I invoice that expense to the client I’d like it to be the same as if I bought something for 1.10$ with no tax. So the tax is shown to me, but the client is invoiced for the gross total.

Hi,

I don’t believe that’s currently supported.
