Please, no!
I think it is necessary a few attempts before finding the optimal configuration. you can possibly create a special configuration separate from the config.pro you use at startup. I used the same for simplicity because I don't have different configuration needs, that's all.
It's been a couple of months but I answer the same, it might be useful.
if you don't print the external square of the sheet then in the config.pro that we use for the pro batch miss the persorso to indicate the format directory used in the table.
It seems impossible, but on the config.pro there is always to put hands.
