I want to edit the the invoice template or create one by myself. There is no option as I am allowed to pick any one from the 6 templates. How it can be done.?

Thanks for your response. I have tried all those options. I can only able to select those 5 templates. But I was looking something else that I can create with a pictured background..., moving the tabs here and there.. etc. which I can't do it.

So my options are limited. Your answer did not provide what I am looking for..
