How can I turn a vassal into a march?

[unmerged(676678)]

Hello,

I just cannot find the button that turns a vassal into a march. I am playing as Poland (1444) and have two vassals. Can someone please explain how it is done?

Thanks!

There's a designate March button in the diplomacy options

Moldavia already starts off as a March so you don't need to do it to them, and making Mazovia a March is a bad idea as you cannot annex a March.
Nonetheless its under the influence actions, it says "Designate March".

Thanks! Now I also found that field in a youtube video, but it does not exist in my game. I have the version 1.8.0.0 (7d1c).

Woops. You're right. I mixed that up with wealth of nations which I bought... Sorry.

Not worthy if you want to annex that land later on

removing march get - 190 relations points takes quite long to regain
and drop stability by one just keep normal vassals instead
