Marker text box location

I am currently dealing with an image where no matter where I place the markers, when they're clicked the text box covers key elements of the image as well as other markers.

If the marker is on the right hand side of the image, the text box appears on the left, and if placed on the left the box appears to the right...so essentially it'll always open towards the centre of the image, which is where the most important part of the image is (and will be in most cases, surely?!). It also covers the other markers.

Why do I have no control over the text box size or location? Trying to work around it in Rise by putting the markers in odd locations is such a pain and it could so easily be solved if there was a 'show text box to left/right' edit option. 

I know the work around is to build it in Storyline and upload it, but that sort of defeats the point.

I don't think there's a solution to it in Rise (unless I'm missing something) - how do I log a suggestion?
