Is it possible to only upload PGP subkeys?

Hello!

Is it possible to upload only encryption and signing subkeys into Mailbox Guard? I do not want to upload my master key, because it is important part of my other workflows. What would be cool, is if mailbox.org supported ADSK (Additional Decryption Subkeys, as per https://gnupg.org/blog/20230321-adsk.html), so that messages could be automatically encrypted for my mailbox.org encryption subkey and secondary encryption subkey not uploaded to mailbox.org, so I can still open my messages even after revocation of mailbox.org encryption subkey.

Is a workflow like that possible?

If anyone is interested, I got answer from helpdesk. Neither subkeys nor ADSK are supported by Guard.

Maybe bit similar topic. i'd like to use also own certificates to sign messages. Like in Thunderbird. That is also not possible. Everything seems to be tied to the generated keys.
