Yes, of course it can be done.
All OxWall is nothing more than a presentation of contents of a database, a usual management of members (profile, registration, etc) and then plugins that do things with this base.
But you should specify well what you want to do to help you.
I understand that it is similar to a spreadsheet for each user and that each user can put what they want in it.
Would it be with fixed-rate fields or something less concrete and more polyvalent?
Can everyone see it or only certain users with certain criteria?
If you do not ask more concrete questions, it is difficult to help you.
