Resize multiple lines at the same time

For some reason, Miro allows you to multi-select several shapes and resize them at the same time, but it won’t let you multi-select several lines in order to resize them. This means that, every time I need to change a set of lines that I want to keep the same length, I either have to delete all but one, stretch that line to the right length, and then duplicate it again OR I need to meticulously, manually stretch each line individually. Please allow multiple lines to be resized at the same time!
