I am trying to group captions with their respective graphs or figures.
If I keep the caption as it is (without a text box) and highlight it
with its graph or figure, I right-click, but there is no option to
group them together. Or, I've tried putting the caption into a text box
and holding control as I try to select both objects, but for some
reason I can't select both. I just want to link graphs/figures with
their captions so that I can add to my paper without worrying about
them getting separated. Any suggestions?

Thanks
