• Auto synchronise text corrections in duplicate textfield, possible?

Hello -

I work in an agency that designs packagings.

Sometimes the back of some packagings are split in two and we have to deliver artworks where for example the nutritional values table has to be duplicated (it depends on the keyline we receive).

The concern we have is that when the nutritional values table is duplicated and the client asks us for text corrections, some designers forget to make the changes in the duplicated table (which originally contains exactly the same information, it has only been duplicated).

From there my question,
is there any way that when someone makes text changes in the table,
these text corrections are automatically made/synchronised in the second table?

I have attached an example of a table, the grey vertical line simulates the split

Thank you,
