customizable fieldset in colnect preview

Current hardcoded fieldset may be great for coins, but for banknotes it sucks (. For example if you need to add a banknote 5 roubles 1905-1912 with signs of Shipov and Mets issued by Soviet government, you have to manually check all 300+ variants, because field containing data with signs does not visible in fieldset.
Another way to fix this problem is to enable group import from colnect. Now you can select some records, but imported would be only one.

Mb it is already done? I had not found how to do it.
