add filter by port

[lazymonkey2]

I'm using the option to load directly the .kdbx local file.
I'm on firefox (sometimes also chrome).

Is it possible to filter saved logins using also port number? (optionally, disabled by default).
I have many localhost logins for different applications I'm developing, and each application has a different port number (using http protocol).
each time I search for a login I get too many entries all related to generic localhost.
