Is it possible to change the suggested email address

Hey everyone, I have a question about Proton Pass. When I register on websites, Proton Pass always suggests my main email address or one of my aliases. I really like using aliases, but I want to change the main email address that gets suggested. I don't like using the same email that I have my Proton account registered with for everything. Is it possible to change the default suggested email address in Proton Pass? Any help or tips would be greatly appreciated! Thanks in advance!
