Multiple registration for one conference with more panels (round tables)

Registration of participants. Example: we have a conference that has 10 panels (each panel is one Zoom webinar). We want to enable participants to have access to all 10 panels (Zoom webinar) with one registration so that they do not have to register more than once. In doing so, we want to have an insight into which participant was individually on which panel (Zoom webinar). As it seems to us for now, each participant would have to re-register for each webinar within the conference, even with e-mail only. Do you have any clever suggestions for solving this problem? Thank you
