I need to list figures and tables in a document, in most cases there is a single numbered figure (Figure 1, Figure 2, Figure 3, etc.) for a specific item, but in a few cases, there are multiples that will have a letter appended (Figure 4A, Figure 4B).

I'm trying to use a multilevel list numbering system, but the multilevel list assumes an outline view. When I set Figure 4 to the second level, instead of 'Figure 4A', it becomes 'Figure 3A'. I need it to start the next number, not be a subset of the previous number, and have all following items with the same level use that number.

Is there a way to achieve the following within a list?

Figure 1
Figure 2
Figure 3
Figure 4A
Figure 4B
Figure 5
etc.
