Repeat section in RTF and add total on each page

I have the following two tables in an RTF document:

• The first table displays data from the DM Header.
• The second table displays data from the DM Lines.

The client has requested that if the second table spans multiple pages, the first table should be repeated at the top of each page.

Is this feasible, especially when the DMs are different? How can it be done?

I tried checking the "Repeat as header row at the top of each page" option on the tables, but it didn't work.

I also have another request: to add the total amount at the end of the table, which should be reported to the next page. On the following page, this total should appear as the amount carried forward from the previous page.
