Hyperspectra line selector improvement/bug

[borondics]

We can already select line profiles in the Hyperspectra widget but I can't seem to manage to add multiple lines using the modifier keys as instructed in the help. This would be a very useful feature.

Hello borondics, have you find a solution for the hyperspectra lines? I just manage to do a profile, but I can not save it nor traces several profiles. I do not find anything helpful in the help.
Thank you in advance for your answer and help.
