I have been Googling a bit and found out that (of course) I am not the only one who's struggling with this. I also found that there has been no effort made by MyHeritage to accomodate this. There's some Dutch software that has this feature but it's an windows software program. I like the online setup of MyHeritage so I can share it with others.
I'll live with it, this is not a serious hobby of me (yet), so it's not thát important to me.
