Zooming with more precision?

Good day.
Is there a way to make your zooming more precise?
Let say with one turn of the mouse wheel you can set it that it will zoom half of what is currently set.

Sometimes in the shop I have a paper template I just want to match what's on the screen and move one without scanning, measuring ect.

Tnx!
