Merge Paint Strokes

Hi guys, Is there a way I can merge multiple Paint Strokes?
I had to write something on a wall and use Strokes (over 250). Now I need to connect the strokes to a tracker but I can't find a way to Connect them all at once.

Thank you!

Click on the Arrow (top of paint toolbar), box-select the strokes you're interested in, then click the Group icon (bottom of paint toolbar). You should now be able to drag/size/rotate all the strokes together.

Thank you very much
