Upload Abstract without creating account

Dear list,

this is the first conference I’m trying to manage in Indico.
A participant can register, pay and even edit their registration data (via private link) without having to create an account.
But when I try to have them upload an abstract, they are forced to create an account. Is there way around this? i.e. is it possible to enable uploading an abstract, without forcing the particpant to create an account?
(We’re using a hosted version, I don’t have access to the innards)

Thank you very much and best regards,

No, accounts are required to submit abstracts
