Yes, there is but the numbers will not, then, work in a ToC or Index.

How to control the page numbering in a Word document and
Page Numbering.
- You will need to insert a SectionPages field in your first section and bookmark that field. To insert such a field, type the word SectionPages and select it. Press Ctrl+F9. That makes it a field. Then press F9 to update it.
- Use Insert > Bookmark to mark it. You need to give it a name: i.e. Section1PageNumber. You can format that to be the color white but not "hidden."
- Go to the header/footer of the page where you want to restart the numbering and use Format Page Numbers to restart the numbering at 1.
- Then construct a field like the following { = { Page } + { Ref Section1PageNumber } } and press F9 to update it.
- When you change the number of pages in your first section, you will need to select your SectionPages field and update it (F9). Ctrl+A followed by F9 may work for you.
- Remember that you cannot simply type the field delimiters {}. You need to use Ctrl+F9 to insert them in pairs.
