Searching user using email address for tagging in comment

It would be better to have a feature so that we can tag a person by searhing their email address.

The problem is that we have global team members working from regions like China & Italy.

Now for example, an Italian person wants to tag a Chinese person named 雨琪 曹 (email address: chi.cao@xxx.com) in comment.

At this moment, it is not possible.

And it is not easy for an Italian person to tag using @雨琪 曹 as they don’t know this language.

But as everyone’s email is in English, so it would be better if we can have a feautre in Workfront to search user for tagging by their email address.

By the way, this searching by email feature is available in proofing comment.
