Freeing up a tight draw

[Mr Edmundo]

With the wealth of information I've gleaned off this and the other site, I haven't seen anything on this.
You can free up the draw on a tight drawing cigar by rolling it gently between your thumb and forefinger. I've done this a few times recently and it worked rather well. Each time I've done it, I've smoked about one third to half of the cigar before I attempted it. The heat and the nicotine seem to moisten up the end so rolling it this way doesn't damage it. Or so it seems in my experience. The result is a much looser draw and a more enjoyable end to the cigar. This brought back memories from years ago, when I used to do it, but have forgotten about it.
I know it would be difficult to recommend doing this because of the risk of damaging the cigar. But in the few times I've recently tried it, I was well into the cigar and had nothing to loose since it was tight anyway. But it worked well.
Does everybody/anybody do this?
The newb in me has to know!
