"Also credited as" - how is this done in IMDB nowadays?

If a person is credited in two different ways (eg in the opening titles versus the closing credits cast list) how is this entered in IMDB nowadays?

At once time there was an attribute "also as..." but that now seems to be blocked by the form validation rules.

An example is "Our House" (1960) {Simply Simon (#1.2)} tt0868453 where actress Ina De La Haye is credited that way in the opening title sequence and as Ina de la Haye in the closing credits. And both names are written in mixed case; neither is written INA DE LA HAYE, so the capitalisation of each is explicit.

Currently this has an attribute "(as Ina de la Haye) (also as Ina De La Haye)" which is displayed as "(as Ina de la Haye, Ina De La Haye)". The second of these credited-as names is superfluous because it is identical to her primary IMDB name.

But when I try to correct the attribute to "(also as Ina de la Haye)", so as to say "she is credited both as her primary name and as a variant of it", I get a red error "This credit has been rejected. You need to correct this credit before it will be accepted. 'also as Ina de la Haye' is not one of the existing attributes we have in this section."

I'm sure I've successfully added/correct attributes like this in the past.

Is there a solution, or should I just stop being so anal (!) and leave things as they are? Maybe just have the "(as... )" and explain this situation in a trivia entry?
