Export Thunderbird account settings (not email) to K9

Using Thunderbird on the desktop. v 102.x.

Just started checking out K9 on Android.

Is there a simple way to import only the account settings from Thunderbird?

Not looking for import of email, sync etc., just account settings.
Message filter import would be a bonus.

Perhaps there is a json or some other file that can be worked with to make this happen?

Have been reading about upcoming sync features etc. after Mozilla’s purchase of K9 - but would be useful to have this account settings import feature now.

Thanks in advance.
