Create a profile from cross-sections

Hello, I would like to ask a question regarding what I suggest in the title, practically it is to be able to place some guide points in the section so that later I can visualize it in the Profile.
I know that the convecional is to make the profile and then display the sections but you can take points that are placed in the section to the profile, it would not have to be just points, perhaps they could be blocks that I place in the section and appear in the profile I leave a guide image on what I want to do
