I'm working on a Word document, and I would like to put two figures side by side, using the same figure number (e.g. Figure 1) but with a letter for each figure (1a and 1b).
What is the cleanest way to do this? I could just add text after the caption and the cross-references, but it would be better if there was a hierarchical way, so that for instance in the list of figures I can see them separately but with indentation.
