It's possible to set a new flag on a treatment which will ensure that every time the treatment is taxated a pop-up will ask for the correct amount of the treatment.
Go to Frontpage - Treatments - List and Treatments and search for the wanted treatment
Find the correct treatment, add the flag called Require count on taxate and press Update.
Taxate the treatment and a pop-up will occur asking for how many treatments should be invoiced.
Choose the correct amount and press Ok in the pop-up( in the example below 3 treatments are invoiced).
