Hi lebirne,
I know the functionality you’re looking for as I’ve seen it before, but it’s not currently possible in Meta Slider. It would require quite a bit of custom CSS work (maybe an hour or 2) so for that reason I’m afraid it’s not something we’d cover under free support – we officially limit free support to bugs, but sometimes we will do the odd custom request if it is a 5 minute job, unfortunately this request is quite a bit more than that.
Regards,
Tom.
