@Lynne-And-Simon0 In my experience, no, you cannot. You are a single entity (human body) and the OTAs treat you as such. I use an email address for my host self on the platforms. When I tried to add a second address as my guest identity so I could travel with a different credit card not associated with my host account, it converted all kinds of things and I had to change it all back.
I now have my host address and ID and I/we frequently travel under my spouse's ID, which is not associated with my host account in any way.
