Reduce character on key license code

Hi, in my company we bought the extension. Now we are trying and we wonder if there is an option to “reduce” the length of the key code.

We don’t want that the user that don’t know how to copy/past a code (i know that is basic…but, we have a very different range of customer) spend so much time writing the code.

How can we do with these?

thank you!
