Solid Hardwood, Engineered and Laminate Flooring - Laminate quarter round End of run cuts???

I am puttiing on laminate quarter round on my baseboards due to not being able to drop my base down to floor height because of paint lines.
I was wondering if anyone else has done this and what they did about end of run cuts, if you miter them like you would regular wood you can see the inside if this (plastic i guess) which is a white color.
If I dont make a miter cut they will stick out pretty good around all my doors, is there a patch kit or stickers available,like the ones you get with a laminate piece of furniture like a entertainment center or is there any other way that i dont see that you can cut your end of run.

Help Please,
Jeff

I little 45º cut piece. This shows them on both ends like if you had two doors along the same wall
