MS Word – How to make different caption style for the table captions in Appendix and main body?

I am trying to create a document where I have different headings and captions for the main body and the appendices. I have created the headings, where I have Chapter 1 and Appendix A (I did this through creating a header 7 for the appendix titles, and changing the number style).

For my tables, I want Table 1, Table 2, … Table A.1, Table A.2, Table B.1 etc

When I create a caption for the appendix, I enter caption, click on format, and tick the box “including chapter headings”. However that changes all my captions in the document. So I either get

Table 0.1, Table 0.2, …, Table A.1, Table A.2

Or Table 1, Table 2, …., Table 8, Table 9

How do I create different captions for the main body and the appendices?
