Well, this request may seem strange, but I need to put the Owner in an object.
And this is not the first time it happens, I felt the need to do it several times in the past, but as I couldn't find an easy way to do it I thought I was going the wrong way in the solutions I was trying to achieve, but I'm beginning to doubt about this.
Also: it shouldn't be too difficult to make this action, so I can't see why it's not yet part of the standard bundle of PM
