Hello, I need to add text in the description of the tasks, by default it comes with collaborative mode activated, so that several users can edit at the same time without problems.

I need, through a button, to add text to the end of the field, up to that point it is simple, but the problem is that if there are users editing that field in collaborative mode, that change is not integrated correctly and when the users save their changes content is lost, 

I would like to know if there is a standard way to do that, or if I have to invent something to solve it.

Thanks
