How to add information to the end of all letters?


Hi, everybody! In the old mailwizz version, I found function that it was possible to add any information to the end of the letter. Now there is such function?
I thank.
And how to make so that the text appeared in the right place to me in letters? For example in the middle.
In footer editor, there is options to set text in left right center. You can select that and set content as you need.

You can also set customer group wise seperate content also.
I thank. I meant that, it is possible както to insert "Email footer" into the middle of the letter? it is possible to eat some variable which can be inserted into the letter that information was displayed not at the end of the letter in that place where I planned it
