Part Length in LPub

[Johann Eisner]

Hello

I am new here in this forum, an so first of all, hello to all.
I already use the search function, but i don´t find a right answer.

Have anyone an idea, how to show the part length from "Technic Flex Hoses" in the BOM of LPub?
The length of axles, beams,... is shown automatically, but not the length of the hoses.

Thanks
Johann
