Has anyone seen a bubble that can be used to mark bottom handrail doubles off with and meet the 470mm requirement from the top handrail.

I'm working on a site where they are not accepting the gap left when simply bubbling down from the top handrail double and the easiest option is to have a slightly longer bubble.

Be much appreciated if anyone has any info.
