[Dovecot] Multiple ssl-certs on different ports with the same protocol

[myleetlist]

Hi,

is it possible to use multiple ssl-certs on different _ports_ with the same 
protocol?
I know I can configure multiple certs with the "local <ip>" setting*.
But how is this (or similar) possible in v2.2.10:

local :100 {
    protocol imap {
            ...
        }
}
local :101 {
    protocol imap {
            ...
        }
}

This would be useful in a loadbalancing setup,
you don't waste IPs and the config files on different servers stay the same.
