I am confused

When I efile T4 slips I do so by creating the XML file and then going into Represent a Client and filing through there. That way I do not need a WAC.

The solution I have had to resort to, is the one that I have seen most often in messages here, that being to go into Efile -- Option --T3/FX and change the transmitter number  so that it agrees with the client's business number

Here is my confusion.

I thought that the many many options settings were set once and then left alone. These are to make the software work as best as possible for each individual user.

So why do we have to change a setting in there for each client

When generating the XML file, why doesn't the software pick up the information that we input into the Employer's account number area.

Why are WE having to do something that the software should be able to do quite easily?
