At the moment, no. I would need to add a toggle that would only append data without modifying any existing values.

That (not only being able to add, but also to remove data) would be a very useful feature for a lot of users, I guess. Well, at least for me

You could manipulate the database with Sciurius' MSPro-Tools https://github.com/sciurius/MSPro-Tools.

Thanks very much for the suggestion. Yes, I know that the database can be manipulated externally, I've done that previously, with irregular results, maybe I should invest more time experimenting. However, I think being able to do that within MS would be much better.
