The trouble with that idea is that “title” is a field you created yourself, it is not fundamentally part of entrywizard. There does not have to be a “title” field.
So the only way I can think of to do what you are asking for would be to set up yet another option on all “image file” fields. And that option would need to specify the field that would hold the new filename/title. Quite a lot of work for me, and more documentation for the admin to plough through.
Also, I imagine you are talking about the original user-generated filename, and not the one used in entrywizard. There would need to be database changes in order to save that, and more code to make sure it does not contain security risks.
— in all, not an easy job, and not one I would have time for in the immediate future.
( I’m also not very happy with encouraging people to confuse the filename, which is essentially a storage location, with a vague concept like “title”. The same image may well be given different “titles” or “captions” depending on the context, but use the same image file. )
