Document Tree Macro - Where to set default limit value

Hello I would like to change default value (15) of children macro (part of Document Tree Macro). Where can I set default value for limit parameter of Document Tree Macro?

There is page for setting limit in navigation panel (/bin/view/Panels/Navigation). I can’t find similar page for Document Tree Macro. BTW to find page for setting in navigation panel wasn’t easy, because there is no link to this page in wiki instance. I have to spend 30 min of googling and forum reading.
