Additional option in advanced search

is it possible to add an addition option to the advanced search ?

there seem to be a few missing such as:

Credited, Credited in part, Draft.

Could this be looked at if it doesnt require too much additional coding.

Cheers

EDIT:-

i see this may not be possible as only full credits for purchases are shown as credited and not the part credits, i guess i’ll have to go through all 288 invoices for this supplier manually to find which ones i have added partial credit notes to, would be easier if there was say a status flag next to the green “paid” to show that invoice has a partial credit.
