Need white line/mark on barrel end of Wyze handheld vaccuum

I’ve just purchased the Wyze handheld battery powered vaccuum cleaner and love it. But I have a design changes I’d like to suggest you make. When removing the canister, the one side has a white line, the other side not. Unless you’re in a well lit area, you can’t see the non-marked side to line up both ends/pieces. Just add a second white line on the barrel of the vaccuum, similar to the end cap section to make it easier to see to line up.
