Extended trend automatic scaling check box

[Mindaugas]

Hello,

I have Extended trend function, to show variables archive data. When the historical extended trend screen opens, to select variable I'm using Extended trend filter function.
I want to ask, how can I do, that automatic scaling check box would be automatically checked, when I add a new variable?
In print screen underlined in red.

I am using Zenon 8.00 version.
