I don't think there is an easier way, unless you don't do it at all.
But then you have the problem when you put your blocks together sometimes they don't quite fit properly.
Then when you fudge it to make it fit you have a quilt with wonky sides...ask me how I know.
I also have a problem with holding my rulers securely when I cut, and it slips and then 3 sides are perfectly square and the 4th is just a smidgen off-then I have to decide if I'm going to work with the smidgen off or just go ahead and trim all them down a smidgen....oh the choices.
