Drawings always changes when I switch between timeframes

 
Hi,

I tried to set a trend line to be orange with thickness 2 (second line on the drp down list) on 4hr EURUSD but when I change my timeframe to 1hr, the line changed to dotted red. How do I change the line permanently to orange with thickness 2 until I decided to change again? When I change back to 4hrs, the line still become dotted red.

And also, if I had 4 charts of EURUSD with different timeframes opened together, how do I make a trendline on one chart auto appear on the other 3 charts (like synchronizing)?
